Abstract
A chromatic dispersion compensation device is provided in the form of an etalon having first partially reflecting mirror providing an input and output port for porting a signal into and out of the etalon cavity. A second partially reflective mirror parallel to and spaced apart from the first mirror, being more reflective than the first mirror provides a monitoring port for monitoring energy within the cavity. Means are optionally provided for controlling a parameter related to the cavity in dependence upon a signal ported from the monitoring port. Means may be provided to control a transmitting laser in dependence upon the signal ported from the monitoring port.
