An InP-based quantum-dot tunable three-section distributed Bragg reflector laser
01 January 2008
A three-section distributed Bragg reflector (DBR) laser operating in the 1550-nm band is reported, based on a quantum-dot gain medium. The device is fabricated using a standard production, full wafer process to achieve a valid comparison with quantum-well-based DBR lasers. A tuning range of 8 nm and a maximum output power of 20 mW are achieved.
