Polarization rotator based on augmented low-index-guiding waveguide on silicon nitride/silicon-on-insulator platform.
Using a newly proposed augmented low-index-guiding scheme with silicon nitride/silicon dual-core waveguide, we have designed, fabricated, and characterized a transverse electric (TE) to transverse magnetic (TM) and TM-to-TE compact polarization rotator. The polarization rotation is realized in an asymmetric directional coupler. The measured peak conversion efficiencies for the TE-to-TM and TM-t...
متن کاملCompact and broadband polarization beam splitter based on a silicon nitride augmented low-index guiding structure.
We propose a compact polarization beam splitter (PBS) based on a silicon nitride enhanced silicon-on-insulator platform using an augmented low-index guiding (ALIG) waveguide structure. In the ALIG structure, the TM mode is mostly confined in the low-index silicon nitride, while the TE mode is confined in the high-index silicon. Since the two modes are confined in two separate layers, their prop...
متن کاملPhotonic Crystal Polarization Beam Splitter in Silicon-On-Insulator Platform
In this work we report an ultracompact (8.7 μm x 10.6 μm) integrated planar photonic crystal polarization beam splitter in silicon-on-insulator platform with 18.6 dB and 11.1 dB extinction ratio at a wavelength of 1520 nm at the outputs for transverse-magnetic and transverse-electric polarization, respectively. The physical separation of both polarization states is achieved by negative and posi...
متن کاملDevelopment of silicon-on-insulator waveguide technology
An overview of the present silicon-on-insulator (SOI) waveguide technology is given and supplemented with an extensive set of theory and simulation results. Characteristics of slab-, rectangularand ridge waveguides in SOI are explained. In particular, the number of modes and the single-mode conditions are carefully analyzed. Experimental work with straight and bent 8 to 10 μm thick SOI ridge wa...
متن کاملEfficient silicon polarization rotator based on mode-hybridization in a double-stair waveguide.
We present a compact silicon polarization rotator (PR) based on mode-hybridization by breaking the cross-sectional symmetry of a double-stair waveguide. The device fabrication is fully compatible with the commonly used silicon photonics processes with no extra masks required. The dependence of device performance on the double-stair waveguide dimensions is investigated using FDTD simulations. Ch...
