Abstract
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 and to etalon fringes. A set of equally-spaced wavelengths may be provided by a set of lasers, or a single laser can be used for a number of fixed frequencies.
