Optical switch based on polymer waveguides

In this paper we present a novel concept of NxN switch with full reconfigurability. A rapid prototyping technique based on direct laser writing is considered as an implementation technology. As a first step towards an NxN switch, the experimentally properties of 2x2 switch are investigated. Several samples of the switch with different coupling lengths and distances between the waveguides are developed. Measurement results of coupling efficiency are presented.
