Abstract
A compact-sized electrically tunable ${\rm TE}$-${\rm TM}$ mode splitter composed of a
mode converter and an asymmetric Y-branch structure is presented. The asymmetric
Y-branch consists of a straight and a bent waveguides to split two polarization
modes based on the mode-sorting effect. To shorten the device length, a simplified
coherently coupled-bending structure is utilized for the bent waveguide. Experimental
results show that the device length is reduced about 52%, extinction ratios
of both ${\rm TE}$ and ${\rm TM}$ modes are higher than 25 dB, yet the applied voltage is not significantly
increased.
