Abstract: A high power optical isolator is able to transfer excess heat to a heat sink, reduce the effect of scattered and reflected light, and be coupled to standard thin optical fibers.

Abstract: An unbalanced Mach-Zehnder interferometer for performing an optical filter on a plurality of optical functions is provided. The interferometer includes a first and second fused tapered couplers to split and combine the light beam. A phase difference media made of glass with different refractive index is inserted between two couplers. This kind of structure can achieve reproducibility and environmental stability such as temperature changes and random bending forces.
