Abstract
A δ-strained InGaAs/InGaAsP MQW modulator has been fabricated and tested. The device shows fully polarisation independent transmission characteristics. Less than 0.80 dB polarisation sensitivity has been achieved for a wide range of wavelength. The extinction ratio is >20 dB at a reverse bias voltage of 3 V. Almost the same Stark energy shift for heavy holes and light holes has been demonstrated in this structure
