Increasing Allowable Channels in Phased Array DWDM Systems

Summary: Purdue University researchers have developed a novel DWDM device that has only one effective order of focusing per wavelength. This device is not limited by harmonic effects, which increases the number of channels that can be multiplexed or demultiplexed.

Technology Benefits: Increases the number of possible channelsOffers more advanced phase modulation techniques Minimizes effects due to physical implementation errors

*Abstract

*Background: Dense wavelength division multiplexing (DWDM) is a new method for solving capacity and flexibility problems in optical communication systems. It offers very large transmission capacity and novel network architectures. The major components in DWDM systems are wavelength multiplexers and demultiplexers, which are limited due to harmonic effects.
