Optical resonant cavity filters |
摘要 |
A wavelength filtering device and system in which an optical resonant cavity is laterally coupled to a trunk waveguide carrying a broad range of wavelengths in the optical spectrum. The filtering cavities may be linear optical fiber segments or fiber segments closed at their ends in the shape of a loop. The devices may include single or multiple optical cavities or hybrid filtering utilizing both dispersive and resonant functions.
