摘要：An optical device comprises: an active semiconductor region (130), for providinggain to signal light (170) passing through said active region (130); a signal-light reflector(120), for reflecting the signal light (170) through the active region (130) in a direction outof the plane of the active region (130); a pump-light reflector (120), the pump-lightreflector (120) being arranged to reflect pump light so as to form a standing wave (160)in the device; and an absorber (191) that absorbs light at a wavelength of the signal light.The absorber (191) is arranged at a position in the device at which there is no orsubstantially no pump light.
