InGaAsP/InP Dual-Wavelength BH Laser

Abstract
A new dual-wavelength BH laser emitting at 1.26 and 1.55 µm has been fabricated. The separation between the two active layers is only 2-3 µm, and independent current injection to each active layer is possible. Simultaneous pulsed operation of the two lasers at room temperature and CW operation at -20°C have been achieved.
