摘要： An optical switch includes a plurality of optical interferometric structures is serially connected between at least one optical input node and two optical output nodes. A primary waveguide directly connects an optical input node and a first optical output node. A complementary waveguide, which is directly connected to a second optical output node, is evanescently coupled with the primary waveguide in a pair of optically coupled sections provided in each optical interferometric structure. Each optical interferometric structure also includes a pair of decoupled sections, which includes a primary decoupled section embedding a portion of the primary waveguide and a complementary decoupled section which includes a portion of the complementary waveguide. The complementary decoupled section is embedded in a phase tuning structure that allows modulation of the phase of the optical signal passing through. The optical switch provides less insertion loss, less crosstalk, and wider bandwidth than prior art optical switches.

摘要： In embodiments of the present invention, a non-blocking quantum interference switch includes a segmented electron wave coupler that splits an electron wave and couples its two parts to two arms of a Mach Zehnder interferometer. A voltage may be applied to an interferometer gate electrode to change the phase of the electron wave traveling in that arm. A second segmented electron wave coupler may receive the two electron waves from the interferometer arms and recombine them into one electron wave. If the two electron waves interfere constructively, then the recombined electron wave exits through one switch output port, which may be a “logical zero” switch port, and if the two electron waves interfere destructively, then the recombined electron wave exits through a second switch output port, which may be a “logical one” switch port.

摘要： In order to provide a low-loss optical switch that is low in power consumption by providing the same as a self-holding type, and high speed and highly practicable, an optical switch of the present invention is composed of a quartz substrate (101), first and second input waveguides (102a and 102b), a first directional coupler (103), first and second arm waveguides (104a and 104b) of a Mach-Zehnder interferometric circuit, a second directional coupler (105), first and second output waveguides (106a and 106b), and a phase change material portion (100). A control light (for an amorphous to crystal transition) pulse (pulse width: 20 ns, pulse intensity: 5 mW) having a wavelength of 0.78 microns is irradiated. As a result of the control light pulse irradiation, the phase change material portion (109) changes in phase to a crystal state, and the optical switch transits to a bar condition.
