Abstract

A high-performance transverse-magnetic (TM) mode-pass polarizer for mid-infrared wavelengths based on a silicon nitride-silicon subwavelength grating (SWG) waveguide is proposed. The designed device supports the Bloch mode for the TM mode only, whereas the transverse-electric mode is reflected by the SWG. Simulations show that with a device length of 7 mu m, this polarizer is capable of achieving an ultrahigh polarization extinction ratio PER) of similar to 50 dB and an insertion loss of similar to 0.3 dB at a wavelength of 2 mu m. The device bandwidth is increased to 60nm for PER > 30 dB. The polarizer also shows good tolerance to fabrication uncertainties. (c) 2018 The Japan Society of Applied Physics
