Optical Mux/Demux
Detailed Technology Description
A new optical micro-structure which has highly dispersive properties and can thus be used to multiplex or demultiplex light for optical communications applications was invented at McGill University. It is a planar device and shares advantages of the so-called photonic bandgap ``superprism`` in that it is more compact than arrayed waveguide gratings and is also not limited by multiple diffraction orders. However, it is superior to currently disclosed superprism designs in that it is more amenable to available fabrication techniques and should display greatly reduced scattering loss.
