Coupled-mode analysis of fiber-optic add–drop filters for dense wavelength-division multiplexing [PDF]
Optics Letters, 1997 We present a coupled-mode theory of fiber-optic add drop filters, which involve directional coupling between two fibers combined with fiber Bragg gratings defined inside the coupling region.

Photonic instantaneous frequency measurement using a dense wavelength-division multiplexer
Applied Optics, 2021A photonic instantaneous frequency measurement receiver based on frequency to optical power mapping is proposed and experimentally demonstrated. One channel of a dense wavelength-division multiplexer (DWDM) is used as an optical filter to establish a power ratio function related to the frequency of the microwave signal.

All-fiber dense wavelength division multiplexers
SPIE Proceedings, 1994Fused and tapered single-mode fiber couplers are used to make polarization insensitive Wavelength Division Multiplexers with a wavelength spacing of around 1 nm. Different structures are presented. As opposed to that of single highly elongated fused couplers, their responses are polarization independent.

Dense Wavelength Division Multiplexer based on Microring Resonators
2018 IEEE Student Conference on Research and Development (SCOReD), 2018This paper demonstrates a dense wavelength division multiplexer (DWDM) based on microring resonators using ring radius variation method. In this design, the spacing between each channel was kept constant at 0.8nm throughout the S, C and L bands. The reference ring size of the ring resonator was 1um.

A novel architecture for dense wavelength‐division multiplexing/subcarrier multiplexing networks
Microwave and Optical Technology Letters, 2001AbstractWe propose and demonstrate a new survivable dense wavelength‐division multiplexing/subcarrier multiplexing (DWDM/SCM) network based on the star–bus–ring architecture (SBRA). This architecture ensures an OBI‐free optical network, and can serve tremendous subscribers. In addition, remote nodes and bidirectional wavelength add/drop multiplexers (B–

Multi-Wavelength Laser Source for Dense Wavelength Division Multiplexing Networks
OFC/NFOEC 2007 - 2007 Conference on Optical Fiber Communication and the National Fiber Optic Engineers Conference, 2007We propose and demonstrate an ITU-T grid compatible DWDM laser source with 50 GHz channel spacing. It consists of a passively mode-locked laser, supercontinuum-generating photonic crystal fiber and fiber Fabry-Perot filter for spectral selection.

We design and model a highly compact and tunable optical add-drop multiplexer (OADM) device that consists of long-period gratings and piezoelectric ceramic fiber stretchers. The proposed OADM shows that 50 dense wavelength-division multiplexing channel signals can be selected in the wavelength range from 1526.25 to 1563.75 nm with 0.75-nm channel ...

Work-Optimal Routing in Wavelength-Division Multiplexed Dense Optical Tori
2008 11th IEEE International Conference on Computational Science and Engineering, 2008We present a 2-dimensional n times n dense optical torus network (DOT ) having p = n2 nodes and l = 2n2 optical links. Each node consists of a processor and of a router. The links are capable of using 2n-1 wavelength channels. Furthermore, we present an all-optical, collision free routing algorithm for the DOT that is based on scheduled transmissions ...
