ABSTRACT: For this SBIR topic, we have proposed a novel high-power optical fiber pump combiner design that addresses the specific challenges associated with counter-pumping large-mode-area (LMA) double-clad gain fibers. Based on modeling and design optimization, we will fabricate kilowatt capable power combiner prototypes for pump coupling to double-clad Yb-doped polarization-maintaining (PM) fi ...

ABSTRACT: We propose to develop and demonstrate a rapid store trajectory analysis tool that uses pre-computed, highly-resolved Detached Eddy Simulation (DES) Computational Fluid Dynamics (CFD) data which has been compressed and stored in an easily reusable and distributable format. The tool will rapidly determine store+bay configurations that display large sensitivity to flow unsteadiness. The te ...

ABSTRACT: Q-Track proposes to develop and demonstrate feasibility of a system for absolute localization in GPS-denied environments. A Signals-of-Opportunity Location Device ("SOLD"), previously demonstrated to yield 1m repeatable location indoors, provides the desired"absolute location reference. Q-Track"s proposed SOLD sensor a compact, lightweight tag ultimately costing about $50 in volume al ...

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 ...

ABSTRACT: The Air Force has identified the need to improve satellite communications by increasing bandwidth, yet seeks to accomplish this without increasing the antenna payload footprint and without introducing vulnerability to transmission interference or jamming. One mature and popular technology explored over the past several decades is a class of engineered materials known as frequency selec ...

ABSTRACT: Princeton Microwave Technology [PmT] is proposing the development of compact microstrip based dual mode resonators for the the design of the low cost diplexers for the GDPAA program.Miniature dual mode resonator based diplexers, in which the main feature and advantage lies in the fact that each of the dual mode resonators can be used as a doubly resonant circuit and therefore requires h ...

ABSTRACT: Wide field of view (WFOV) video capability on unmanned aerial systems (UAS) has outpaced data transmission capability. Identifying regions of interest (often performed though object recognition) enables selective video compression and maximizes the useful content in data transmission. Neuromorphic classifiers currently hold the records for greatest accuracy of object recognition and spe ...

ABSTRACT: Discovery Semiconductors will assemble high power InGaAs/InP photodiodes with 50 ohm internal termination in a fiber-pigtailed, W1-connectorized microwave package having the following specifications: (a) Responsivity>0.7 A/W at 1550 nm wavelength; (b) -3 dB Bandwidth>60 GHz; (c) -9 dB Bandwidth>80 GHz; (d) 1 dB Compression Photocurrent>50 mA @ 60 GHz modulation frequency and>50% mo ...

ABSTRACT: The feasibility of developing a prototype traveling-wave scanning system based on non-metallic, broadband, optical-fiber-coupled microwave-field sensors that can be used for the test and evaluation of coatings applied to the surface of aircraft without damaging the coating layers is investigated. The concepts to be employed in performing the measurement of microwave surface waves will b ...

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 ...
