Variable Index Material For Optical Switching And Real Time Holographic Recording
US Patent:
5472786, Dec 5, 1995
Filed:
Sep 19, 1994
Appl. No.:
8/308856
Inventors:
Keith H. Pannell - El Paso TX

Jean Robillard - El Paso TX
Assignee:
Board of Regents, The University of Texas System - Austin TX
International Classification:
B32B 904
US Classification:
428447
Abstract:
A new variable index material is described which provides rapid changes in refractive index. The disclosed materials are useful for coatings and films that provide photosensitive materials for holographic recording with high efficiency. The materials are also useful for modulating the coupling ratio in fiber optic couplers for optical switching. The new materials incorporate polymeric dialkylsilane ferrocenylene and long chain fatty acids.
