Novel Approach for Controllable Polarization Beam Splitter: Design and Simulation

Abstract

A novel controllable polarization beam splitter is designed by using the modified Y-branch waveguide structure, in which the nematic liquid crystal is introduced. The optical performance of the polarization beam splitter is numerically investigated by the beam propagation method. The results show that not only can high extinction ratio and low optical loss be easily achieved, but also the output ports for TE and TM modes can be dynamically interchangeable in our configuration. Moreover, the proposed polarization beam splitter has little wavelength dependence and large fabrication tolerance. This firstly proposed device provides a unique approach for the manipulation of polarization splitting, which has wide potential application in the photonic integrated circuits.

Design of a photonic crystal fiber polarization beam splitter with simple structure and ultra-wide bandwidth

“…in optical communication and sensing systems. [1][2][3][4][5] It is mainly used to separate the light beams in the orthogonal polarization directions. [6][7][8][9] Over the past two decades, photonic crystal fiber (PCFs) have received great attention due to their unique optical characteristics.…”

Design and analysis of Wilkinson power divider using 2D photonic crystal

“…Wilkinson power divider is a popular power divider because it is easy to construct and has some extremely useful properties like it is matched at all ports, output ports have large isolation, and most importantly when the output ports are matched it is reciprocal and lossless. There is symmetry in the circuit and it can be exploited to make the S parameter calculations easier [8][9]. The rest of the paper is organized as follows: The design and simulation of Wilkinson power divider and the design and analysis of modified Wilkinson power divider is detailed in Section II.…”
