ABSTRACT: This project aims to develop a Short Wave Infrared band image projector to provide real time detector stimulation with high dynamic range. Our emitter technology is based on GaInAsSb quaternary semiconductor LED arrays hybridized to CMOS read-in integrated circuits. This project leverages read-in circuit design and control electronics that were developed under SLEDS - a longer wavelengt ...

ABSTRACT: In this SBIR effort we will develop a packaging process and demonstrate (Phase I) a prototype of high power Photodiode (PD) that has a normal incident, pigtailed fiber input and a coaxial RF output that operates from DC to>60GHz. We will apply and extend (Phase II) the aforementioned packaging process to single PD, balanced PD and array of PDs that work from DC through entire W-band. De ...

In this proposal we will develop a general method for fabricating 3D polymer based Photonic Crystal structures (PhCs) with engineered defects. The criterions of such a method include the generality of producing various periodic arrangements of 2D, 3D PhCs with or without aperiodic features, compatibility for different polymer materials and their synthetic processes, batch manufacturability for low ...

Identifying a means of accurately simulating the scattering and radiation from large objects and scenes in a reasonable timeframe has been an active area of research for decades. Traditionally, addressing this problem has required either trading accuracy and flexibility for performance or running simulations on massive platforms such as supercomputers. Due to lingering limitations, these approac ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

The determination of information provenance in order to establish trust about sources of information and its subsequent quality is an important aspect of information management. The volume of digital information and the scale of its growth, both in terms of proliferation of sources as well as the size of digital information, presents a myriad of problems in their management. Validity and quality a ...
