Cross Connect

Abstract An all optical cross-connect for communications networks is presented here. Optical switching is accomplished in a planar silica lightwave circuit where the switching array matrix is defined by a system of intersecting waveguides. Small microchannels are fabricated at the waveguide intersection and are filled with an index matched liquid. Microbubbles are thermally manipulated to allow light to be either transmitted or reflected by total internal reflection. The physics associated with the bubble behavior and the requirements of a reliable package present a slew of challenges for the mechanical engineer.

Frustrated Total Internal Reflection

Two optical methods, namely surface plasmon resonance imaging and frustrated total internal reflection, are described in the paper in terms of comparing their sensitivity to change of refractive index of a thin boundary layer of an investigated medium. It is shown that, despite the fact that the theoretically calculated sensitivity is higher for the frustrated total internal reflection method, and the fact that usually in practice the surface plasmon resonance method, on the contrary, is considered more sensitive, under the same experimental conditions both methods show a similar result.
