Recent Study on LiTaO3 Directional Coupler Switch with Enhanced Extinction Ratio and Low Insertion Loss

The R-Soft CAD programme was used to create a unique optical directional coupler switch with S-bend waveguides on a LiTaO3 substrate, which was then simulated using the Beam propagation method (BPM) for light propagation analysis. The optical directional coupler (ODC)
