Abstract
A laser () and detector () integrated on corresponding epitaxial layers of a single chip () cooperate with on-chip and/or external optics () to couple light of a first wavelength emitted by the laser to a single external device such as an optical fiber () and to simultaneously couple light of a different wavelength received from the external device to the detector to provide bidirectional photonic operation. Multiple lasers and detectors may be integrated on the chip to provide multiple bidirectional channels.
