Abstract

Polarization handling devices are essential elements in photonic integrated circuits. In this paper, a phase shifter for applying different phase shift on transverse electric (TE) and transverse magnetic (TM) modes is presented. By optimizing a strain-enhanced InGaAsP multiquantum well structure the birefringence is increased and the phase shift between TE and TM modes is enlarged. The simulation results indicate that with a low driving voltage of 2 V and a small length of 2 mm, a 2π phase shift difference between TE and TM modes over 100 nm wavelength around the c-band is achieved.
