Ruggedized, Ultra-Compact, High Dynamic Range, Dual-Output Wideband Electro-Optic Modulator

In this SBIR effort we will develop and analyze (Phase I) a new design and packaging approach for an ultra-compact, dual-output wideband Mach-Zehnder modulator (MZM) for low noise figure (NF) and high dynamic range radio-frequency (RF) photonic link applications. We will provide (Phase I) experimental proof-of-concept of the proposed device by tailoring our current 100GHz MZM product. In Phase II, we will optimize the modulator and package design based on Phase I experimental results, and fabricate, package and characterize the modulator prototype to meet the design specifications. Special attention will be given to testing the hermetically sealed modulator package under extreme environment following guidelines of DOD test standards. The demand of such a compact dual-output electro-optical (EO) modulator arose from the recent progress in various RF photonic link systems using balanced detection scheme to achieve short noise limited NF performance and modulation OIP3 limited spurious free dynamic range (SFDR). PSI has a unique background to perform this work based on over 10 years"experiences in developing high-speed (up to 300GHz) lithium niobate (LN) modulators and recent success in packaging high-power MUTC PDs that have been employed to realize positive link gain up to 30GHz.
