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 ...

Grating spectrograph in InGaAsP/InP for dense wavelength division multiplexing
Applied Physics Letters, 1991A grating spectrograph in InGaAsP/InP suitable for use in the wavelength region from 1.2 to 1.6 μm is presented. Experiments for devices with a channel spacing of 3.7 nm and more than 30 channels between 1.48 and 1.59 μm are described. The measured cross talk level is below −25 dB. The devices have only very low polarization sensitivity.

Dense Wavelength Division Multiplexing Networks: Principles and Applications
2009The very broad bandwidth of low-loss optical transmission in a single-mode fiber and the recent improvements in single-frequency tunable lasers have stimulated significant advances in dense wavelength division multiplexed optical networks. This technology, including wavelength-sensitive optical switching and routing elements and passive optical ...
