Abstract
Polarisation-independent operation of an unstrained InGaAsP/InGaAsP multiquantum well electroabsorption modulator is reported. Contrast ratios of 20 and 30 dB for 400 μm long devices have been achieved at 2.0 and 5.5V reverse bias voltage, respectively, with on-state attenuation less that 2 dB and at 1.55 μm wavelength. Polarisation sensitivity at these voltage values is found to vanish
