Abstract
An AlGaAs/GaAs graded-index-waveguide separate-confinement-heterostructure (GRIN-SCH) single-quantum-well (SQW) laser has been monolithically integrated with a couple of field-effect-transistor drivers on a semi-insulating GaAs substrate. The adoption of the GRIN-SCH SQW laser has enabled an improvement in the laser/FET performance, exhibiting a low laser threshold current (12 mA) and a high sensitivity of the output light power to the input gate voltage (7.5 mW/facet/V).
