Abstract
An optical transceiver supports bidirectional communication with another optical transceiver that is a communications partner via a single-mode optical fiber. A surface emitting laser has a T-band oscillation wavelength that is shorter than the cutoff wavelength of the optical fiber. A photodetector has detection sensitivity with respect to the T band. A planar lightwave circuit couples the optical fiber, the surface emitting laser, and the photodetector.
