We report the first semiconductor optical amplifiers at 2.0-μm wavelength, heterogeneously integrated by bonding an InP-based active region to silicon. On-chip gain larger than 10 dB is observed at 20°C over a 40-nm bandwidth. OCIS codes: (130.3120) Integrated optics devices, (230.4480) Optical amplifiers.

We present an integrated optical isolator based on adiabatic wavelength conversion in microcavities. The isolator uses a time-division sampling method to ensure complete isolation of optical pulses with an extinction of 24 dB. ©2009 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (230.3240) Isolators.

We demonstrate frequency stabilization of a continuous-wave laser using an integrated TiO2 athermal cavity as a reference for the first time, and show linewidth improvement by a factor of 6 compared to a SiN cavity.

A wavelengthand bandwidthtunable filter with microelectromechanical-system (MEMS)actuated waveguides is first demonstrated on a silicon-based microdisk resonator. Integrated microheaters enabled wavelength tuning up to 125GHz. Bandwidth can be tuned from 12.0 to 41.2GHz by coupling control. © 2005 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (140.4780) Optical re...
