Chalcogenide glasses, with high nonlinearity and low loss, have captured research interest as an integrated device platform for near- and mid-infrared nonlinear optical devices. Compared to silicon-based microfabrication technologies, chalcogenide fabrication processes are less mature and a major challenge is obtaining high quality devices. In this paper, we report a hybrid resonator design lev...

This Chapter covers recent advances in Short Wavelength Infrared (SWIR), Medium Wave‐ length Infrared (MWIR) and Long Wavelength Infrared (LWIR) materials and device technol‐ ogies for a variety of defense and commercial applications. Infrared technology is critical for military and security applications, as well as increasingly being used in many commercial products such as medical diagnostics...

AN INFRARED DEVICE TO MEASURE THE EYEBLINK FOR THE STUDY OF CLASSICAL CONDITIONING By Alka Patel The classically conditioned eyeblink response is studied by various groups to study neurological functions. This is a form of associative learning that has many features to help diagnose and learn about neurological diseases. Electromyogram traditionally is used to detect eyeblinks for this experime...

BACKGROUND Current cancer management faces several challenges, including the occurrence of a residual tumor after resection, the use of radioactive materials or high concentrations of blue dyes for sentinel lymph node biopsy, and the use of bulky systems in surgical suites for image guidance. To overcome these limitations, we developed a real-time, intraoperative imaging device that, when combi...

We report the use of PbS nanocrystals within a hybrid device that emits 1.2 m electroluminescence with an external quantum efficiency of 1.15% corresponding to an internal quantum efficiency of 5% –12% thus demonstrating a viable, low-cost, highly efficient near infrared organic electroluminescent device. Direct generation of the excited state on the nanocrystal result in eliminating competing ...

MnZn ferrite thin films were deposited on p-Si substrate and used as the dielectric layer in the graphene field effect transistor for infrared and terahertz device applications. The conditions for MnZn ferrite thin film deposition were optimized before device fabrication. The infrared properties and terahertz wave modulation were studied at different gate voltage. The resistive and magnetic MnZ...

Objective: Today, there are various non-invasive techniques available for the determination of blood glucose levels. In this study, the level of blood glucose was determined by developing a new device using near-infrared (NIR) wavelength, glass optical waveguide, and the phenomenon of evanescent waves. Materials and Methods: The body's interstitial fluid has made possible the development of ne...

Infrared thermal microscopy is a widely used tool for the thermal analysis of microelectronic circuits [1]. It is a noncontact measurement technique and utilizes naturally emitted infrared radiation from a sample. Commercial IR microscopes are readily available, offering a maximum spatial resolution of ~ 3 μm and a range of analysis options, including real time thermal mapping and thermal trans...
