Ruggedized Ultra-compact, High-Dynamic-Range, Dual-Output Wideband Electro-Optic LiNbO3 Modulator Navy SBIR FY2014.2 Sol No.: Navy SBIR FY2014.2 Topic No.: N142-100 Topic Title: Ruggedized Ultra-compact, High-Dynamic-Range, Dual-Output Wideband Electro-Optic LiNbO3 Modulator Proposal No.: N142-100-0007 Firm: EOSPACE Inc 6222 185th Ave. NE Suite 100 Redmond, Washington 98052 Contact: Suwat Thaniyavarn Phone: (425) 869-8673 Web Site: www.eospace.com Abstract: The proposed effort is to develop and package a new ultra-compact, wideband, dual-output electro-optic LiNbO3 modulator for RF/photonic link applications on air platforms. The modulator will be capable of extremely high optical power handling (>500mW), and have dual outputs for use with balanced photo receiver which would enable a higher link gain, a lower noise figure and a higher spur free dynamic range. The modulator will be capable of 40GHz bandwidth, and compatible with future extended operation to 100GHz for new emerging systems. The modulator will be in a ruggedized package with less than 5 mm in height, a volume of <2.5 cubic centimeters, and is capable of uncooled operation over -40 to +100 degrees Celsius and maintain hermeticity and optical alignment upon exposure to typical Navy air platform vibration, humidity, thermal & mechanical shock, and temperature cycling environments. Benefits: The replacement of the coaxial cable used in various onboard RF/analog applications with RF/analog fiber optic links requires ruggedized, high dynamic range, dual-output wideband electro-optic modulators. The development of high performance modulators with very small size, weight and power (SWaP) will enable practical implementation of RF analog fiber-optic links to replace coaxial cabling on airborne platform to increased immunity to electromagnetic interference, reduction in size and weight, and an increase in bandwidth of operation.
