    摘要: The present invention discloses an optical switching element that uses reversible electroplating mirrors includes a trench with transparent sidewalls located at the intersection of two waveguides A and B. The trench has two electrodes; one, which is transparent, is placed on the trench sidewall and the other is placed on the trench floor. The trench is filled with an index-matching electrolytic solution containing ions of a metal that can electro-deposit on these two electrodes. To actuate the switching element, a negative electrical potential is applied to the sidewall electrode. Actuation causes metal deposits to form on the sidewall electrode, creating a mirror that reflects light from waveguide A to waveguide B. To deactivate the switching element, a positive electrical potential is applied to the sidewall electrode. Deactivation causes metal deposits move off the sidewall and form on the trench floor. The lack of metal deposits on the sidewall allows light to pass through the switching element and continue along the original waveguide A

    摘要: This invention discloses an optical device that includes a wavelength-selective optical transmission system. The wavelength-selective optical transmission system further includes a first waveguide for transmitting a multiplexed optical signal therethrough. The wavelength-selective optical transmission system further includes a second waveguide coupled to the first waveguide wherein a least one of the first and second waveguides having a set of wavelength-selective Bragg gratings disposed near a coupling section between the first and second waveguides. One of the first and second waveguides has an aspect ratio, i.e., a ratio of a thickness divided by a width, is no greater than 0.75.

    摘要: The present invention is a wavelength-selective optical transmission system that includes a first waveguide for transmitting a multiplexed optical signal therethrough. The system further includes a second waveguide coupled to the first waveguide wherein a least one of the first and second waveguides have a set of wavelength-selective Bragg gratings disposed near a coupling section between the first and second waveguides to reflect a reflecting optical signal back to the first waveguide and for transmitting a contra-directional optical signal and a co-directional optical signal having respectively a contra-directional selected wavelength and a co-directional selected wavelength corresponding to the Bragg gratings. One of the contra-directional and co-directional wavelengths is chosen as a designated wavelength, and the reflecting optical signal and one of the contra-directional or co-directional optical signals are outside of a predefined range surrounding the designated wavelength.
