    Abstract: A switchable device for changing the opacity of at least a portion of a glazing is described. The switchable device comprises at least two (a first and a second) switchable regions in electrical communication with at least two (a first and a second) electrical connector regions. Each switchable region comprises an electrically actuated variable opacity layer between a first electrode and a second electrode, the first switchable region being arranged relative to the second switchable region such that upon connecting the first and second electrical connector regions to a suitable power supply, the opacity of the first and second switchable region changes such that at least two (a first and a second) portions of the switchable device have a change of opacity, the first portion of the switchable device having a different opacity to the second portion of the switchable device.

    Abstract: An optical modulator for switching an optical signal of wavelength λ from one waveguide-electrode to another requires that both waveguide-electrodes be made of an electrically conducting material. Also, a non-conducting cross-coupling material fills a slot along a length L between the waveguide-electrodes. Importantly, cross-coupling material in the slot provides a separation distance xc between the waveguide-electrodes that is less than 0.35 microns. When a switching voltage Vπ is selectively applied to the waveguide-electrodes, a strong uniform electric field E is created within the cross-coupling material. Thus, E modulates the cross-coupling length of the optical signal by an increment ±Δ each time it passes back and forth through the cross-coupling material along the length L. Thus, after an N number of cross-coupling length cycles along the length L, when NΔ equals one cross-coupling length, the optical signal is switched from one waveguide-electrode to the other.

    Abstract: An optical modulator module includes: a substrate in which a plurality of optical modulators are formed; a connector configured to include a plurality of terminals to which a plurality of signals for driving the plurality of optical modulators are input; and a relay board provided between the substrate and the connector. Each of the optical modulators includes an optical waveguide, a modulation electrode formed near the optical waveguide, and a feeder electrode electrically connected to one end of the modulation electrode. The terminals are arranged in parallel to a longitudinal direction of the substrate. Positions of respective ends of the modulation electrodes at which the respective feeder electrodes are electrically connected are the same as positions at which the respective terminals are provided in the longitudinal direction. Wiring patterns are formed on the relay board so as to electrically connect the terminals to the respective feeder electrodes.
