Large-Scale and Simple-Configuration Optical Switch Enabled by Asymmetric-Port-Count Subswitches
IEEE Photonics Journal, 2016 We propose a novel optical switch architecture for intra-datacenter interconnection. The proposed switch consists of asymmetric-port-count delivery-and-coupling (DC) switches and wavelength-routing (WR) switches based on arrayed-waveguide gratings (AWGs).

Chirality in Nonlinear Optics and Optical Switching [PDF]
Molecular Crystals and Liquid Crystals, 1993 Chirality in molecular opto-electronics is limited sofar to the use of optically active liquid crystals and a number of optical phenomena are related to the helical macroscopic structure obtained by using one enantiomer, only. In this paper, the use of chirality in nonlinear optics and optical switching is demonstrated.
