A wavelength division multiplexed optical network has a restoration process to re-route one or more of the wavelengths, by dynamically determining possible restoration routes, and re-routing each wavelength along a chosen one of the possible restoration routes. A distributed dynamic search for restoration routes down to the optical layer, for wavelengths, gives faster and more scalable restoration than reconfiguring routing tables and enables much better utilisation of bandwidth than using predetermined restoration paths.

Multilayer thin film reflectors, such as mirrors and reflective polarizers, are described in which form birefringent optical layers are incorporated into a plurality of optical repeat units in the film. The form birefringent layers exhibit birefringence as a result of microscopic structures that have a dimension that is small compared to the wavelength of light but large compared to molecular distances. The optical layers within the optical repeat units have out-of-plane indices of refraction that are tailored to produce desired effects as a function of incidence angle for p-polarized light. The multilayer reflectors can be made by conventional vacuum deposition techniques using known inorganic optical materials, but can also be made entirely with polymeric materials by co-extrusion or other processes.

Protuberances, having vertical and lateral dimensions less than the wavelength range of lights detectable by a photodiode, are formed at an optical interface between two layers having different refractive indices. The protuberances may be formed by employing self-assembling block copolymers that form an array of sublithographic features of a first polymeric block component within a matrix of a second polymeric block component. The pattern of the polymeric block component is transferred into a first optical layer to form an array of nanoscale protuberances. Alternately, conventional lithography may be employed to form protuberances having dimensions less than the wavelength of light. A second optical layer is formed directly on the protuberances of the first optical layer. The interface between the first and second optical layers has a graded refractive index, and provides high transmission of light with little reflection.
