Abstract
An optical device is provided which locks the wavelength output of a laser transmitter in an optical transmission system as well as preventing the propagation of unwanted signals generated by the laser transmitter prior to the transmitter reaching the desired operating wavelength thereby reducing crosstalk between channels within a wavelength division multiplexed communication system.
