InP-based polarization rotator-splitter for mid-infrared photonic integration circuits

InP-based polarization rotator-splitter for mid-infrared photonic integration circuits

We design and experimentally demonstrate the propagation loss of waveguides and the operation of a single-step etched polarization rotator-splitter (PRS) in low index contrast InGaAs-InP material system at 6.15 μm. Propagation losses 4.19 dB/cm for TM mode and 3.25 dB/cm for TE mode are measured. Th...
