Zusammenfassung:This letter demonstrates an InP-based photonic integrated circuit that utilizes an etched facet and a dual port multimode interference reflector to create a lasing cavity. The laser was fabricated using UV lithography and did not require any epitaxial regrowth. A single deep etched slot produced single mode behavior due to the coupled cavity effect. By varying the bias of the two sub cavities, mode selectivity with a side mode suppression ratio of 30 dB is demonstrated.
