Mode locked distributed Bragg reflector laser

Summary form only given. Mode locked semiconductor lasers are important for a wide range of fiber transmission systems. These include soliton generation and clock recovery in very high speed transmission systems. Compact, single chip, mode locked lasers are desirable for practical systems since they are likely to be more stable than the offchip external cavity designs. The fabrication and performance characteristics of a single chip mode locked laser is reported here. The laser emits near 1.55 /spl mu/m and is fabricated using the InGaAsP/InP material system.
