Polarization sensitivity of birefringent photorefractive holograms and its applications to binary switching
Abstract:
The effect of polarization sensitivity on the intensity and the resolution of the diffracted beams from a birefringent photorefractive hologram is investigated. In addition, an optical switching technique based on the sensitivity is demonstrated. The method is capable of implementing a large number of 2 x 2 switching channels with only four holograms. The on/off ratio of the switches can easily reach 100:1. This switching methodology is applicable to either synchronous or asynchronous interconnection with a variety of photorefractive materials.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
