Abstract
The superprism effect is one of unique dispersive properties of PCs that has been proposed for integrated wavelength demultiplexing. However, diffraction of separated wavelength channels has been a main drawback in such PC demultiplexers. We demonstrate in this talk new compact PC demultiplexers by combining diffraction compensation and the superprism effect with better resolution, smaller size, lower crosstalk, and less demanding requirements on the input beam compared to other proposed PC demultiplexers. PC devices demonstrated experimentally here have at least one order of magnitude better performance compared to other reported demonstrations of PC superprism-based demultiplexing.
