Abstract:
1. A remotely configurable add/drop for a WDM optical network, comprising: a primary refracting body having a total internal reflecting surface and capable of transmitting optical energy therethrough; an optical filter, optically aligned with a first surface of said primary refracting body, that configurably passes selected wavelengths of light through said primary refracting body and reflects remaining wavelengths; a first collimating lens optically aligned with a surface of said optical filter; a second collimating lenses coupled to a second surface of said primary refracting body; a frustrating refracting body located proximate said total internal reflecting surface and having a mirror; and an actuator, coupled to said primary refracting body and said frustrating refracting body, that drives said frustrating refracting body between an open state, in which said add/drop processes said selected wavelengths, and a closed state, in which said add/drop leaves said selected wavelengths substantially intact.
