Defect Formation in Optoelectronic Nanoparticle Films Under Extreme Illumination Conditions

Nanoparticle-film-based solar cells and photodetectors are of interest for deployment in a wide variety of extreme environments, both on earth and in space. Specifically, films formed from colloidal quantum dots (CQDs), nanometer-sized semiconductor fragments, have the advantage of inexpensive solution-based processing, mechanical flexibility, and infrared responsivity. However, the stability of CQD film-based materials under high temperatures and illumination levels is known to be a problem. Physical and electronic defects in the films form under extreme conditions that are detrimental and sometimes fatal to device performance; however, the defect formation mechanism and physical nature are not well-understood. We propose to study the formation and evolution of defects under extreme illumination conditions in nanoparticle-based optoelectronic thin films using spatially-resolved photoluminescence and photocurrent measurements. This work will answer fundamental questions about the identity, formation pathways, and consequences of the defects in CQD-based films under high illumination levels and temperatures. Using the results of our studies, we will also develop strategies to improve the stability of CQD-film-based solar cells and photodetectors under extreme conditions.

Wide- Field Scan-Less Multi Photon Endoscopy Using Spatio-Temporal Pulse Delivery and Temporal Focusing

The focus of this proposal is to develop a novel, high energy pulse delivery technology by using coherent imaging fiber bundles in conjunction with a two-dimensional spectral disperser at the proximal end of the fiber bundle and demonstrate its application to multi-photon endoscopy. First (Aim 1), we will use a twodimensional spectral disperser in order to decompose high energy laser pulses into 𝑁 spectral slices, each with a fraction (1/𝑁) of the total bandwidth, mapped to 𝑁 different cores in a multi-core fiber. Second (Aim 2), we will investigate design of a miniaturized distal assembly that includes an achromatic micro-objective, a pair of miniaturized tube lenses, and a dichroic prism. Third (Aim 3), we will utilize pseudo-random structured illumination and compressed sensing image recovery in conjunction with the developed technologies in order to reduce the impacts of tissue scatter and thus improve the imaging depth of the micro-endoscope. Ultimately, this technology will enable a compact, temporally focused micro-endoscope for high-speed imaging of neural activity in behaving animals.

Development of heterogenous platform for chip-based quantum information applications

The past decade has seen numerous promising photonic devices for quantum information in various platforms including bulk geometries, optical fibers, and more recently, photonic chips. To satisfy the scaling, robustness, and cost requirements necessary to enable pervasive implementation of quantum communication technology, a silicon-compatible platform is essential. Nevertheless, it is becoming clear from current advances in chip-based photonic technology that no single material will be able to provide all the functionalities necessary to build a full scale quantum network. To realize this vision a novel three-dimensional heterogeneous photonic platform is proposed in which each material layer or a combination of coupled layers offers optimal performance for a specific functionality such as indistinguishable single-photon sources, quantum frequency conversion, and quantum storage.

AUTOMATED SMART STETHOSCOPE FOR DIAGNOSING CHEST AUSCULTATIONS  

The use of chest auscultations to “listen” to and diagnose lung infections has been in practice since the invention of the stethoscope in the early 1800s. While it is a versatile tool that is universally used , it remains an outdated technology that has not evolved much beyond its early design. Proposed is the design of a novel, smart stethoscope that will automate diagnosis of chest auscultations; especially for pediatric use. Over 2 million children die every year of acute lower respiratory infections (ALRI), the leading cause of childhood mortality worldwide. The project develops a programmable technology that not only delivers a high-quality signal even in very noisy environments, but can automatically detect lung pathologies; hence providing a triage tool that enhances resource and case management of ALRI, especially in impoverished settings that lack alternative tools or high medical expertise.

DEVELOPING OPTICAL SENSOR GUIDED MICRO-SURGICAL TOOLS FOR OPHTHALMIC APPLICATIONS

Contemporary microsurgery is performed by very skilled and highly trained surgeons using binocular operating microscopes, free hand techniques and manually operated micro-surgical instruments. The results are therefore often limited by a surgeon’s skill level and the capabilities of the available tools.  To overcome the “human limitations” an interdisciplinary team led by Professor Kang have developed practical and usable “SMART” vitreoretinal micro-surgical tool technology directed at enhancing the surgeon’s freehand ability to achieve surgical objectives, diminish surgical risk and improve outcomes. This technology could drastically improve surgical performance compared to using free-hand surgical tools.

Compressive Imaging Beyond One Trillion Frames Per Second

This research program will develop a video imaging system operating at frame rates beyond one trillion frames per second and that is capable of recording isolated (non-repetitive) events. No current camera technology can operate at these extremely high frame rates and video durations for the observation of isolated events. Such a high-speed single-shot imaging system is an enabling technology for numerous applications throughout engineering and the physical and life sciences. In particular, we plan to leverage the ultrafast single-shot imager developed through this program to better understand the dynamics of materials under extreme conditions.

Neuronal mechanisms of perceptual organization in the primate visual system

The visual brain infers a three-dimensional world from two-dimensional images and organizes the visual information in terms of objects in three-dimensional space, representing even objects that are partially occluded and appear fragmented in the retinal image. This organization is the basis for attentive selection, action planning and object recognition. A combination of experimental and theoretical studies together with model implementations in neuromorphic hardware will be used to elucidate the interface between visual feature representations and attentive cognitive processes.

Optical Coherence Tomography Image and Sensor Guided Microsurgical Tools with Enhanced Surgical Functions

Contemporary microsurgery is performed by very skilled and highly trained surgeons using binocular operating microscopes, free hand techniques, and manually operated micro-surgical instruments. The results are therefore often limited by a surgeon’s skill level and the capabilities of the available tools. To overcome the “human limitations” an interdisciplinary team led by Professors Kang and Gehlbach have developed practical and usable “SMART” vitreoretinal micro-surgical tool technology directed at enhancing the surgeon’s freehand ability to achieve surgical objectives, diminish surgical risk, and improve outcomes. The principal aim of this work is to validate this novel technology toward communization. The approach is to quantitatively determine whether OCT distal sensor and image guided SMART micro-surgical tools reduce surgical risk and improve outcomes.

Smart Stethoscope For Monitoring and Diagnosis of Lung Diseases

We propose to design a novel smart stethoscope to automate diagnosis of chest auscultations, especially for pediatric use. More than 2 million children die every year of acute lower respiratory infections (ALRI), the leading cause of childhood mortality worldwide. By improving diagnosis capability using a low-cost technology, the proposed smart stethoscope will enhance resource and case management of ALRI, especially in impoverished settings that lack alternative diagnosis tools such as X-rays.

Next Generation of Surgical Imaging and Robotics for Supervised Autonomous Soft Tissue Surgery

Anastomosis is a critical procedure in reconstructive surgeries, particularly in gastrointestinal (GI) surgery. More than a million anastomoses are performed in the US each year for GI, urologic, and gynecologic surgeries. Up to 30% of GI anastomoses are complicated by leakage, strictures, and stenosis. These complications are attributable in part to technical and technologic issues, and they can significantly diminish the quality of life for affected patients and increase patient mortality rates. The long-term goal of this research is to reduce complications and improve functional outcomes of anastomosis by robotically executing best anastomosis techniques. This research has the potential to significantly improve the function and outcome of anastomosis, independent of surgeon experience. Beyond anastomosis, adoption of this approach could be beneficial in all soft tissue MIS and RAS tasks requiring precision and maneuverability due to small working space, including pediatric and complex cardiac surgery.

Tongue Muscle Function After Cancer Surgery Using 4D, MRI, DTI, and MR Tagging

In the case of tongue cancer treatment through glossectomy, there is often significant post-treatment morbidity including difficulties in speech and swallowing and sleep apnea. In this project, we will optimize existing imaging and imaging analysis methods to enable a novel capability for the assessment of surgical outcomes in tongue cancer surgery. Our goal is to better understand the impact of tongue cancer treatment on speech in order to avoid significant morbidity by modifying surgical practice or engaging in specific speech therapies after surgery.
