A novel coherent optical receiver is proposed and experimentally demonstrated by using a feedback technique capable of reducing the nonlinear distortion in a traditional receiver while retaining the signal to noise ratio. ©2006 Optical Society of America OCIS codes: (060.1660) Coherent communications; (120.5060) Phase modulation

A highly integrated homodyne receiver has been demonstrated within a footprint of 1 cm. The receiver successfully receives 40 Gbit/s BPSK and error free is achieved up to 35 Gbit/s. Theoretical analysis has been also carried out showing the feasibility of integrated 16 QAM homodyne coherent receivers.

An integrated variable delay receiver for DPSK optical transmission systems is presented. The device is realized in silicon-on-insulator technology and can be used to detect DPSK signals at any bit-rates between 10 and 15 Gbit/s.

A theory for the signal-to-noise ratio (SNR) of optical direct-detection receivers employing return-to-zero (RZ) coding (and possibly optical preamplification) is developed. The results are valid for both signal-independent noise limited and signaldependent noise limited receivers, as well as for arbitrary optical pulse shapes and receive filter characteristics. Even if the same receiver bandwi...

An optoelectronic integrated circuit (OEIC) receiver is realized with standard 0.25-μm SiGe BiCMOS technology for 850-nm optical interconnect applications. The OEIC receiver consists of a Si avalanche photodetector, a transimpedance amplifier with a DC-balanced buffer, a tunable equalizer, and a limiting amplifier. The fabricated OEIC receiver successfully detects 12.5-Gb/s 2(31)-1 pseudorandom...

A new microphotonic mm-wave receiver architecture with direct electrical-to-optical conversion is presented. The receiver uses high-Q RF and microphotonic electro-optic resonator components which are operated in simultaneous resonance. Initial results demonstrating modulation of an optical carrier at RF in the mm-wave range are reported .
