Design and analysis of high performance phase shifters on polymeric slot waveguides within liquid crystal cladding

Abstract We present an on chip phase shifter based a polymeric slot waveguide and liquid–crystal cladding, which is capable of reaching high tuning ranges, low control voltages propagation losses. Our analysis includes purely numerical 3D-Finite-Difference-Time-Domain method semi-analytical 2D-Finite-Element-Method approach. Both analyses are in agreement, confirm the performances. have used analytical order to study values voltages, electrostatic simulations validate approximations. Moreover, addition waveguide, we show that it possible develop Y-Splitters with negligible insertion losses same technology, enables this type shifters adapt existing platforms optical integrated circuits, significantly enhancing their modulation capabilities.
