Abstract
The design of a high modulation response multiple-quantum-well ridge w aveguide laser in AlGaAs-GaAs, with low parasitics is discussed. The d evice was fabricated on a semiinsulating substrate with a wide top con tact, and airbridges have been used to connect the ridge top contact t o the bonding pads on the semi-insulating substrate. The 3-dB frequenc y response of the laser has been measured to be 21 GHz, which is a rec ord for unstrained quantum-well AlGaAs-GaAs lasers.
