چکیده

A polarization converter consisting of a silicon waveguide is analyzed by the imaginary-distance beam propagation method based on Yee’s mesh and the finite-difference timedomain method. It is revealed at a wavelength of 1.55 μm that the polarization conversion length is 15.1 μm with an insertion loss of 0.47 dB. An extinction ratio of more than 20 dB is obtained over a wavelength range of 1.53 to 1.57 μm.

Photonic Crystal-Based Polarization Converter for Optical Communication Applications

A photonic crystal-based TE to TM polarization converter for integrated optical communication is proposed in this paper. The photonic crystal consists of air circular-holes in slab waveguide. The radius of holes are determined to be 291nm having lattice constant of 640nm using the gap map and band diagram. The polarization converter is composed of an InGaAsP triangular-shaped waveguide on SiO2 ...

Group velocities in coplanar strip transmission lines on Si and Si/SiO2/Si substrates measured using differential electro-optic sampling

The group velocities in coplanar strip transmission lines on Si and Si/SiO2/Si substrates were compared experimentally and theoretically. To ensure the experimental accuracy, a differential electro-optic sampling system with a delay-time resolution of 30 fs and a spatial resolution of 1 mm has been developed. Compared with the group velocity on a Si substrate, the group velocity on a Si/SiO2/Si...

Ultracompact polarization converter with a dual subwavelength trench built in a silicon-on-insulator waveguide.

The design and fabrication of an ultracompact silicon-on-insulator polarization converter is reported. The polarization conversion with an extinction ratio of 16 dB is achieved for a conversion length of only 10 μm. Polarization rotation is achieved by inducing a vertical asymmetry by forming in the waveguide core two subwavelength trenches of different depths. By taking advantage of the calibr...

A photonic-plasmonic mode converter using mode-coupling-based polarization rotation for metal-inserted silicon platform

We present a photonic-plasmonic mode converter using modecoupling-based polarization rotation for connecting a silicon wire and hybrid plasmonic waveguides on a metal-inserted silicon platform. By using the polarization rotator based on defect-introduced silicon wire waveguide, the proposed mode converter can convert the photonic TE mode into the hybrid plasmonic TM mode. At the beginning, to i...
