In this SBIR effort we will develop a balanced detection analog photonic link consisting of a DFB laser, a dual-output high-speed, low-Vp mach-zehnder modulator (MZM) and a high-power, high-linearity balanced photodetector (BPD) using a dual-core, single mode, multicore fiber (MCF) that is supplied by our subcontractor, OFS. We will design, fabricate and characterize (phase I) the MZM and the BPD, ...

A high-fidelity RF/Analog fiber-optic link based on a balanced photodetection using a dual-output modulator and a balanced photodetector pair offers significant improvement in RF gain, low noise figure (NF) and enhanced spur-free dynamic range (SFDR). It requires the use of path-length matched dual fibers to achieve proper noise cancellation. The objective for this SBIR is to develop a balanced fi ...

Photonic integration, and specifically silicon photonics, has emerged as one of the leading solutions for maintaining or improving the performance of optical systems while addressing the requirements related to size, weight, and power (SWaP). Photonic integrated circuits (PICs), which integrate multiple photonic elements onto a single chip, are specifically suited to providing the complexity and f ...

The objective of this proposal is to demonstrate the feasibility of producing a decentralized, scalable, rapidly deployable system to treat wastewater streams with high total suspended solids (TSS) content to: 1. Recover a clean, pathogen-free water output that meets potable drinking water standards 2. Recover a dried, pathogen-free solid material, and 3. Optionally recover a concentrated solution ...

Automated and Efficient Extract Transformation and Labeling of Textual Data in a practical, rigid and structured way. 200 million characters per hour deterministic formal machine translation of raw and ambiguous documents. • Common input file types include; pdf, doc, ppt, txt, csv, xls, html, etc. • Structuring is 100% accurate (hash value provable) • Structuring and labeling is ...

In phase II work, we will collaborate with Prof. Stefan Preble in RIT and continue to develop large scale hybrid integration and packaging techniques for key active photonic components such as lithium niobate on insulator (LNOI) modulators and modified uni-traveling (MUTC) photodiodes. We will demonstrate a low V, broadband, small footprint LNOI modulator with hybrid Si/LN or SiN/LN waveguide usin ...

To reach the end user, oil and gas production at the wellhead must be transmitted through the country and distributed to a wide range of customers. This logistical system requires natural gas gathering lines, processing facilities, product storage tanks and lots of other equipment. What results is air pollution caused by industry losses during these operations and the use of continuous or intermit ...

Fungal skin infections plague active duty servicemembers at elevated rates due to exposure to warm, humid climates, poor skin hygiene, and close-quarters living arrangements. We have developed a novel solution that incorporates an endophytic fungal extract with selective activity against Trichophyton species of pathogens. In addition, the selected compound has negligible impact on the organisms th ...

Lightweight Polymer Matrix Composites (PMCs) and metal structures in military and commercial aircraft, can often be subjected to complex damage requiring bonded repair. The current repair method involves time-consuming, costly, and often unreliable thermal surveys to control thermal uniformity which often results in tedious trial-and-error experimentation. Convergent Manufacturing Technologies US ...

In support of the Hi-FIVE effort in wideband HF communications, optimized frequency selection, and improved parametric settings for signal control, NWRA will employ our extensive HF propagation software capabilities.Given an ionosphere estimate from our GPSII code, informed by current measurements (including WSPRnet and other amateur-radio databases), we can efficiently characterize the propagatio ...
