Abstract

A high-performance InP-based polarization beam splitter (PBS) using a symmetrical Mach–Zehnder interferometer is experimentally demonstrated. The waveguides are aligned along the [011] direction, which results in a small reverse bias required and easy adjustment to realize the PBS. The experimental results indicate that the polarization extinction ratio (PER) is over 19 dB in the wavelength range from 1525 to 1570 nm with one arm injected with a 4.32 mA current and the other arm reversed biased at 5.14 V simultaneously. The PER is measured to remain above 18 dB in the same wavelength range even when the width varies by $\pm 200\mathrm{nm}$.
