Polarization insensitive wavelength conversion in a dispersion-engineered silicon waveguide
We experimentally demonstrate polarization-insensitive all optical wavelength conversion of a 10-Gb/s DPSK data signal based on four-wave mixing in a silicon waveguide with an angled-pump scheme. Dispersion engineering is applied to the silicon waveguide to obtain similar four-wave mixing conversion performances for both the TE and TM modes. Bit-error rate measurements are performed and error-f...
متن کاملResonant Tunneling Three-Waveguide Polarization Splitter
We propose the design of a novel and highly efficient all-dielectric, three-waveguide polarization splitter based on the phenomenon of resonant tunneling. By considering a glass waveguide structure with an intermediate high-index guiding layer (such as silicon), we show that one can obtain extinction ratios better than -30 dB in both the outer waveguides at a particular thickness of the high-in...
متن کاملA Split-Block Waveguide Directional Coupler
A simple waveguide directional coupler is described which uses the split-block type of construction common in millimeter-wave components. The coupler uses an array of metal probes suspended on quartz stand-offs. Depending on the number of coupling elements, the coupling can be in the range 15-30 dB, with typically ± 2 dB variation across the waveguide band, and directivity > 10 dB. The coupler,...
متن کاملA submicron broadband surface-plasmon-polariton unidirectional coupler
The manipulation of light propagation is a basic subject in optics and has many important applications. With the development of nano-optics, this area has been downscaled to wavelength or even subwavelength scales. One of the most efficient ways to control light propagation is to exploit interference effects. Here, by manipulating the interference between two nanogrooves on a metal surface, we ...
متن کاملLow loss coupler to interface silicon waveguide and hybrid plasmonic waveguide
A metallic coupler is proposed to interface a silicon on insulator (SOI) waveguide with a narrow hybrid plasmonic waveguide (200× 200 nm). The device operation is investigated and optimized to attain the best tradeoff between the mode confinement and the propagation loss. Calculations reveal that a high confinement and low loss of the energy is achieved from a silicon slab waveguide into the di...
