Wavelength demultiplexing structure based on arrayed plasmonic slot cavities.
A compact wavelength demultiplexing structure based on arrayed metal-insulator-metal (MIM) slot cavities is proposed and demonstrated numerically. The structure consists of a bus waveguide perpendicularly coupled with a series of slot cavities, each of which captures SPPs at the resonance frequency from the bus waveguide and tunes the transmission wavelength by changing its geometrical paramete...
متن کاملDual wavelength demultiplexing by coupling and decoupling of photonic crystal waveguides.
We demonstrate that the fundamental mode of the two coupled photonic crystal waveguides (PCWs) can be odd parity in a triangular photonic crystal and their dispersion curves do intersect. Thus, the PCWs are decoupled at the crossing point. By employing the decoupling at the crossing-point frequency and ultra short coupling length for another frequency, we designed a dual-wavelength demultiplexe...
متن کاملWavelength-division multiplexing and demultiplexing on locally sensitized single-mode polymer microstructure waveguides.
A four-channel wavelength-division-(de)multiplexing [WD(D)M] device, operating over optical wavelengths of 543.0 to 632.8 nm, has been successfully fabricated on newly developed locally sensitized polymer (photo-lime gelatin) microstructure waveguides (PMSW's). The WD(D)M device exhibits a cross talk of less than -40 dB between adjacent channels and a diffraction efficiency of better than 50%. ...
متن کاملWavelength Demultiplexing Structure Based on Coupled-Cavity Waveguides in Photonic Crystals
A structure based on photonic crystals for optical wavelength demultiplexing is proposed and analyzed. This structure consists of two coupled-cavity waveguides, each one tuned at a different frequency transmission band. A model based on the tightbinding method taken from solid-state physics is used to design the working frequencies of the waveguides. The demultiplexing behavior is demonstrated ...
متن کاملWavelength demultiplexing by chirped waveguide gratings
The performance of a chirped waveguide grating as a wavelength demultiplexer has been investigated. Considerations include TE-‘LX, TE-TM and TM-TM mode coupling for different incident angles and waveguide parameters. The spectral response of the chirped sinusoidal surface relief grating in the optical waveguide has been studied by means of Local Normal Mode Expansion (LNME) theory to account fo...
