Optimized Design and Simulation of a Compact TFLN-Based Integrated Device for Simultaneous Polarizing and Equal-Power Beam Splitting

Optimized Design and Simulation of a Compact TFLN-Based Integrated Device for Simultaneous Polarizing and Equal-Power Beam Splitting

We present a compact thin-film lithium niobate integrated device simultaneously achieving high polarization extinction ratio and equal-power beam splitting, using two optimized oppositely-tapered graded-slope mode converters monolithically integrated with a multimode interference coupler. The conver...
