摘要：

A wide optical gain spectrum with full width at half maximum Delta lambda approximate to 350 urn has been demonstrated in midinfrared (2.2-2.5 mum) room-temperature-operated InGa(As)Sb/GaSb quantum-well (QW) ridge-waveguide diode lasers. A QW width of 200 Angstrom ensured a small energy separation between the first and second quantized states in the QW. Transitions from both quantized states contributed equally to the overall gain spectrum when the optical loss was optimized. (C) 2001 American Institute of Physics.
