Strained In0.2Ga0.8As/GaAs multiple quantum well polyimide buried ridge waveguide lasers with 3 dB bandwidths of 20 GHz and K factors as low as 0.17 ns have been fabricated. This is the highest bandwidth and the lowest K factor reported to date for quantum well lasers in any material system or for lasers of the ridge waveguide geometry.
