摘要： A semiconductor-based tunable add/drop method and apparatus. In one aspect of the present invention, a method according to an embodiment of the present invention includes splitting a first optical beam having multiple wavelengths into second and third optical beams with a first 3 dB optical coupler disposed in a semiconductor substrate. Portions of the second and third optical beams having a tunable wavelength are reflected back to the first 3 dB optical coupler with first and second pluralities of silicon and polysilicon interfaces, respectively, disposed along the semiconductor substrate. In another embodiment, the portions of the second and third optical beams having a tunable wavelength are reflected back to the first 3 dB optical coupler with first and second pluralities of modulated charged regions. Portions of the second and third optical beams not reflected are directed to a second 3 dB optical coupler disposed in the semiconductor substrate. The portions of the second and third optical beams not reflected are combined into a fourth optical beam with the second 3 dB optical coupler.
