Compact low-birefringence polarization beam splitter using vertical-dual-slot waveguides in silicon carbide integrated platforms
文献摘要：
The polarization beam splitter is a key component for polarization manipulation in photonic integrated circuits,but it is challenging to design for low-refractive-index optical materials,due to the low birefringence of the wave-guides.We propose what we believe is a novel compact vertical-dual-slot waveguide-based coupling scheme for silicon carbide,enabling efficient low-birefringence polarization splitting by extensively modulating the trans-verse-magnetic mode distribution.We numerically and experimentally demonstrate the device in the 4H-silicon-carbide-on-insulator integrated platform,with a small footprint of 2.2 μm×15 μm.The device,easy to fabricate via a single lithography process as other components on the chip,exhibits low insertion loss of＜0.71 dB and＜0.51 dB for the transverse-electric and transverse-magnetic polarized light,respectively,and polarization extinction ratio of＞13 dB,over 80 nm wavelength range.
