Planar arrayed waveguide device structure for 2D wavelength demultiplexing

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...

Wavelength 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...

4 Arrayed Waveguide Gratings

Arrayed Waveguide Grating Router

This paper discusses design, fabrication, and characterization of a 512 × 512 arrayed waveguide grating router (AWGR) with a channel spacing of 25 GHz. The dimensions of the AWGR is 16 mm × 11 mm and is fabricated on a 250 nm silicon-on-insulator platform. The measured channel crosstalk is approximately −4 dB without any compensation for the phase errors in the arrayed waveguides. The AWGR spec...

A Demultiplexing Scheme Using an Arrayed- Waveguide Grating for a Dwdm Mm-wave Fiber- Radio System by Optical Frequency Interleaving

Introduction Recent progress in transmission capacity of dense wavelength-division multiplexed (DWDM) signals in a trunk optical fiber line now allows transmission of data beyond 10 Tbit/s over more than 100 km [1], [2]. The DWDM technology has to be applied to future millimeter-wave fiber-radio systems in order to take the capability to deal with the large amount of data capacity. There have b...
