Abstract
A bi-directional optical transmission system comprises an emitter chip, a detector chip, and an optical fiber. An outgoing beam generated by the emitter chip is coupled into the fiber, which also transmits an incoming beam. The detector and emitter chips are arranged in a side-by-side configuration such that the detector chip receives part of the incoming beam. In one embodiment, a thin-clad edge-emitting laser diode is used to reduce power loss of the incoming beam.
