Abstract
Novel architectures of integrated optical add/drop wavelength division multiplexers and FTIR switches are disclosed. In one embodiment, an add/drop includes: (1) a primary refracting body having a total internal reflecting surface and capable of transmitting optical energy therethrough, (2) a frustrating refracting body having a frustrating surface located proximate the total internal reflecting surface, (3) an actuator, coupled to the primary refracting body and the frustrating refracting body, that drives the frustrating refracting body thereby to frustrate a reflection of the total internal reflecting surface and (4) an optical filter, optically aligned with the primary refracting body, that configurably passes selected wavelengths of light through the primary refracting body and reflects remaining wavelengths.
