Bilayer Silicon Nitride Based On-chip Polarization Rotator for O-band Photonic Applications

We present a compact polarization rotator design based on bilayer SiN that can convert TM input light to TE and vice versa. Polarization rotation is achieved by mode evolution, the device comprising of an escalator, rotator, and taper sections.
