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; a frustrating refracting body having a frustrating surface located proximate said total internal reflecting surface; an actuator, coupled to one of said primary refracting body and said frustrating refracting body, that drives at least one of said refracting body toward one of said frustrating refracting body thereby to frustrate a reflection of said total internal reflecting surface, said primary refracting body and said frustrating refracting body configured to reflect a beam of light in a first direction when said total internal reflecting surface is not frustrated and reflect said beam of light in a second different direction when said total internal reflecting surface is frustrated; and an optical filter, optically aligned with said primary refracting body, that configurably passes selected wavelengths of said beam of light through said primary refracting body and reflects remaining wavelengths.
