Workpackage 2: WDM Components |
| ||||||||||||||
This workpackage addresses the issue of tailoring the wavelength response of high-contrast photonic microstructures. The use of high refractive index contrast microstructures yields compact devices with a very sharp wavelength response, but also places a high demand on fabrication accuracy. One aspect of this workpackage is therefore to establish the precision that we can routinely achieve in the fabrication of dispersive elements, another is to develop devices that can tolerate a certain degree of inaccuracy using novel designs. The starting point is devices that have already been demonstrated (by partners and elsewhere) and refining them both theoretically and experimentally, optimising for dispersion strength, beam quality and low loss.
