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 ...

Because of the overwhelming migration to composites, particularly exotic thermoset materials from the bismaleimide (BMI) family, the PNTS team is focusing its work on this topic on composite structures. The team's high level approach will be to demonstrate an innovative and practical design using dielectric spectroscopy at millimeter wave through terahertz frequencies that will provide compos ...

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: 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 ...

Traditional Information Fusions (IF) systems need to be expanded to encompass a decision support system (DSS) role that enables analysts and commander to manage the volume and heterogeneity of sensor data, including the textual"soft"data descriptive of the social cultural landscape characteristics of contemporary missions. To achieve these improvements, SoarTech, supported by NCSU, will develop Se ...

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 ...

Millimeter-wave RADAR imaging holds significant promise for many applications from rotorcraft DVE mitigation to standoff security screening. A key challenge of this imaging modality, however, has been the implementation of an effective method for creating an image without relying on either mechanical scanning or expensive, high SWAP phased array techniques. Herein, we present a concept for creat ...

Soar Technology, Inc. (SoarTech) proposes to integrate detailed models of cultural daily activities and patterns of life into simulations of synthetic characters inhabiting, and of vehicular traffic moving in, an urban environment. SoarTech will demonstrate technical feasibility of the approach by integrating these models into the Army's OneSAF in a way that requires minimal resource utilizat ...
