| Abstract: | Minimum threshold current density of 0.57 kA/cm/sup 2/ and high T/sub 0/ values up to 74 K were obtained from 400 mu m long broad area lasers with MOVPE grown compressively strained all-quarternary GaInAsP SCH-MQW layer structures for 1.53 mu m emission wavelength. With 3 mu m*400 mu m RW laser diodes (T/sub 0/>90 K) high-temperature CW operation up to 130 degrees C was achieved.<> |
