RECONFIGURABLE MULTICHANNEL TRANSMITTER FOR DENSE WAVELENGTH DIVISION MULTIPLEXING (DWDM) OPTICAL COMMUNICATION

摘要

A high performance reconfigurable DWDM transmitter incorporates discrete optical components placed in v grooves etched in a substrate. Direct wavelength monitoring can be achieved with wavelength modulation locking applied independently to a gas absorption line (108) and to etalon fringes (112). A set of equally-spaced wavelengths may be provided by a set of lasers, or a single laser (102) can be used for a number of fixed frequencies.
