Abstract. We propose and demonstrate for the first time an optical single-sideband (OSSB) modulation generation based on silicon-on-insulator coupled-resonator optical waveguides (CROWs) capable of operating at wide bandwidth with enhanced sideband suppression. The optimum order of the CROW filter was synthesized based on comprehensive performance analysis including optical sideband suppression and electrical power variation. Experimental results demonstrate an OSSB signal with sideband suppression as large as 23 dB. The performance of the proposed OSSB was demonstrated via compensating radio frequency (RF) power degradation in the transmission of the RF signal within the fiber.

Abstract:We describe recent progress in integrated microwave photonics in wideband signal processing applications with a focus on the key signal processing building blocks, the realization of monolithic integration, and cascaded photonic signal processing for analog radio frequency (RF) photonic links. New developments in integration-based microwave photonic techniques, that have high potentialities to be used in a variety of sensing applications for enhanced resolution and speed are also presented.
