Langmuir-Blodgett films in a waveguide optical pick-up head using Mach-Zehnder interferometers |
摘要 |
An integrated optical head has first and second channels forming an interferometer. A electro-optically phase-shiftable waveguide channel is associated with one of the first and second channels of the interferometer for electro-optical phase shifting of one channel with respect to the other channel. The interferometer is formed on a silicon substrate and the phase-shiftable waveguide channel is formed of Langmuir-Blodgett thin-film electro-optic polymers described on the silicon substrate.
