Planar buried heterostructure InGaAsP multiple quantum well (MQW) lasers consisting of six InGaAsP (lambda/sub g/ = 1.34 ..mu..m at room temperature) wells and five InP barriers were prepared by low-pressure metalorganic chemical vapor deposition. The threshold current was 35 mA, and the differential quantum efficiency was 45% at an emission wavelength of 1.3 ..mu..m. In the temperature range from -35 to 30 /sup 0/C, the characteristic temperature was T/sub 0/ = 57 K. No significant improvement in T/sub 0/ was observed in these MQW lasers. However, stable single longitudinal mode operation could be obtained in a wide range of injection current without any mode changes. This effect was considered to be a result of gain narrowing of the MQW lasers.
