Abstract: A bypass-exchange switch (102) for switching the path of at least one optical signal (92a) includes a telecentric imaging device (104) for high efficiency coupling of the optical signal into either of two outputs (90b,90d). The switch also includes an optical director (106) for changing the operating mode of the switch from an exchange state to a bypass state wherein the different outputs are selected. The optical director is implemented as a variable reflectivity mirror, or a mechanically-actuated mirror. The switch may include a wavelength selective filter for permanently bypassing or exchanging preselected wavelengths of the optical signals.

Abstract: In accordance with the invention, a WDM optical communication system includes a new tunable multi-channel dispersion compensating filter (13) having low loss, low polarization dependence and capable of compensating many channels over a large wavelength range. In essence, the filter comprises an optical cavity (27) with a near 100% reflector (29) on one side and a variable partial reflector (19) on the other side. The device acts as a tunable all-pass filter.
