Abstract

A simple photonic integrated circuit consisting of a ring laser, a passive waveguide and a detector has been fabricated in GaAs/AlGaAs. A ring laser is employed as a source in this circuit because it is easily integrated with other components on the same substrate. The detector monitors the counterpropagating mode of the ring laser and shows no leakage current. The structure is easily fabricated by straightforward lithography and does not require overgrowth.
