Notes:
Lasing characteristics have been investigated systematically in long-wavelength InGaAs separate confinement heterostructure quantum well laser diodes (SCH QW LD's) with varied well thicknesses and number of wells, for the first time. Marked improvements in threshold current density and characteristic temperature values have been observed in SCH MQW LD's to SCH SQW LD's. Maximum cw output power of 46 mW at 20 °C has been achieved in SCH QW LD's with five wells, which is the highest among the long-wavelength quantum well LD's.
