GaAs-based Uncooled Integrated Compact Analog Transmitter Navy SBIR FY2015.2 Sol No.: Navy SBIR FY2015.2 Topic No.: N152-085 Topic Title: GaAs-based Uncooled Integrated Compact Analog Transmitter Proposal No.: N152-085-0702 Firm: Applied Optronics 2008 Eastpark Blvd Cranbury, New Jersey 8512 Contact: Dennis Tishinin Phone: (908) 753-6300 Abstract: In response to the Navy need for an uncooled optical transmitter operating at a wavelength near 1 micrometer, Applied Optronics (AO) proposes to develop a GaAs-based Uncooled Integrated Compact Analog Transmitter (UNICAT), comprised of the following integrated components: a frequency-stabilized high-power laser, an integrated high-speed modulator, and power optical amplifier. By using GaAs platform, UNICAT will be able to achieve full RF transmitter functionality in temperature range -40 0C to 100 0C with high power >100 mW, low noise Benefits: The direct application for UNICAT system is to interconnect RF boards on a single ship or air vessel, where all distances are less than few hundred meters. Replacement of coaxial RF cables with fiber optic links will reduce electromagnetic interference, improve on size and weight, and increase bandwidth for data transfer. However, with further improvements on SFDR and bandwidth, the potential military applications of UNICAT technology become numerous, especially for phased array systems. Examples include: Phased Array Radar, Communications (including CATV), Electronic warfare, Millimeter-Wave imaging, and True Time Delay systems. Other examples include Photonic Switched Solid State Antenna, Antenna Beam Forming and Beam Steering, and large-area distributed RF detection systems. The civilian applications of UNICAT optical link may include: Radio over Fiber (RoF) applications, Radio over Free Space (RoFS) systems, ultra-dense cable television (CATV). Return
