Tunable polarization beam splitting based on a symmetrical metal-cladding waveguide structure

Optical Devices Based on Symmetrical Metal Cladding Waveguides

Conical reflection of light during free-space coupling into a symmetrical metal-cladding waveguide.

Novel conical reflection of light by a thick three-layered metal-clad optical waveguide is observed. A symmetrical metal-cladding optical waveguide is used, which exhibits extraordinary conical reflection during free-space coupling of light to the waveguide. The phenomenon is attributed to the leakage of excited ultrahigh-order guided modes and their inter- and intramode coupling interaction.

Tunable polarization beam splitter based on optofluidic ring resonator.

An efficient polarization beam splitter (PBS) based on an optofluidic ring resonator (OFRR) is proposed and experimentally demonstrated. The PBS relies on the large effective refractive index difference between transverse-electric (TE) and transverse-magnetic (TM) polarization states, since the silica-microcapillary-based OFRR possesses a slab-like geometry configuration in the cross section th...

Optimization of a Birefringence - Enhanced - Waveguide - Based Polarization Beam Splitter

waveguide (BWG)-based polarization beam splitter (PBS) in a Mach-Zehnder interferometer (MZI) configuration and analyze the structure-dependent or polarization-dependent phase difference, using a delay-line MZI (DL-MZI). We fabricate the DL-MZI using silica-based planar lightwave circuit technology and, using the DL-MZI, demonstrate the ability to optimize a PBS by measuring the birefringence o...

Propose, Analysis and Simulation of an All Optical Full Adder Based on Plasmonic Waves using Metal-Insulator-Metal Waveguide Structure

This paper proposes a full adder with minimum power consumption and lowloss with a central frequency of 1550nm using plasmonic Metal-Insulator-Metal (MIM)waveguide structure and rectangular cavity resonator. This full adder operates based onXOR and AND logic gates. In this full adder, the resonant wave composition of the firstand second modes has been used and we have ob...
