Highly reliable 1.55-/spl mu/m strain compensated multiple quantum well distributed feedback ridge waveguide lasers grown by single step MOVPE

Strain compensated multiple quantum well distributed feedback lasers emitting at 1.55 /spl mu/m have been fabricated by single step metalorganic vapor phase epitaxy on patterned substrates. The lasers demonstrate high device yield with high performance and stable operation, at a constant output power of 10 mW, over 1300 hours at 25/spl deg/C and 300 hours at 50/spl deg/C.
