摘要:
A transmitter/receiver including a stack of semiconductor layers with an active layer 12 and a diffraction grating 16 with a phase shifter 18. A tapping electrode 30 is formed above the phase shifter in order to tap a voltage whose variations reflect the frequency modulation of a light beam propagating in the active layer. A bi-directional optical link is formed by connecting multiple transmitter/receivers according to the invention together via optical communication lines. The present invention finds particular application in the field of optical telecommunications.
