This device works as an optical isolator from the cut-off frequency of the lowest forward wave (lower frequency) to one for the lowest reverse wave (higher frequency). This inhomogeneity induces a propagation constant shift, which is propagation-direction-dependent. Align a Faraday isolator ensures optimal transmission of optical power from the source, as well as effective suppression of reflections traveling back toward.

At least one part of the cross-section is a non-reciprocal magneto-optic medium, which has nonzero off-diagonal permittivity tensor components. The cross-section of the waveguide is inhomogeneous in terms of materials. Embodiments are characterized by a cutoff frequency for forward propagating waves that is different than the cutoff frequency for reverse waves the dimensions and direction of magnetization of the. Embodiments comprise a waveguide section utilizing materials that induce a propagation constant shift that is propagation-direction-dependent. Lasers benefit from isolators by preventing backscatter into the laser, which is detrimental to their performance. Various optical isolator embodiments are disclosed. Isolators have two ports and are made for free-space and optical fiber applications.
A particular embodiment is constructed as a single-mode waveguide on a substrate. An optical isolator is a device that allows light to travel in only one direction. These include narrowband and broadband configurations that operate in spectral ranges. Embodiments are characterized by a cutoff frequency for forward propagating waves that is different than the cutoff frequency for reverse waves the dimensions and direction of magnetization of the waveguide can be tailored so that, in a particular embodiment, the cutoff frequency for forward propagating waves is lower than the cutoff frequency for reverse waves. Photonwares provides a wide selection of fiber optical isolators/circulators covering most of the application scenarios. These isolators offer 1 MW/cm 2 CW damage threshold and 10 J/cm 2 10 ns or 1 J/cm 2 8 ps pulse damage thresholds. Various optical isolator embodiments are disclosed. Our high power Faraday optical isolators can be used in the 1010 nm to 1080 nm wavelength range and provides double escape ports for applications where rejected power exceeds 0.5 W.
