摘要： Systems and methods for controlling and measuring modes possessing even and odd symmetry in a slow-light photonic crystal waveguide. An example device comprises a photonic crystal waveguide having modes possessing even and odd symmetry, and a Mach-Zehnder coupler comprising two waveguide branches one of which has a phase adjuster. Another example device, which can be used as an optical isolator, comprises two Mach-Zehnder couplers, and a photonic crystal waveguide comprising an electro-optic modulator therein. A method of measuring a group index of a mode with odd symmetry comprises: coupling light into a photonic crystal waveguide through a Mach-Zehnder coupler with a mixed even/odd symmetry, measuring insertion loss of the combined light signal after passing through the photonic crystal waveguide, determining the spacings of adjacent peaks or valleys from the insertion loss versus wavelength plot, and using the spacings to determine the group index of the odd symmetry mode.

摘要： A phase shifter includes an optical waveguide, a plurality of impurity regions and a plurality of electrodes. The optical waveguide receives an optical input signal and outputs an optical output signal. The impurity regions include respective charge carriers. The impurity regions are disposed in contact with the optical waveguide at respective contact surface, where at least one of the contact surfaces has a zigzag pattern. The electrodes are connected to the respective impurity regions. Application of an electrical signal to at least one of the electrodes phase-shifts the optical output signal with respect to the optical input signal. Therefore, the phase shifter may efficiently vary a magnitude of the phase shift of the optical output signal.

摘要： In an electro-optic device, a stack structure including a first silicon layer of a first conductivity type and a second silicon layer of a second conductivity type has a rib waveguide shape so as to form an optical confinement area, and a slab portion of a rib waveguide includes an area to which a metal electrode is connected. The slab portion in the area to which the metal electrode is connected is thicker than a surrounding slab portion. The area to which the metal electrode is connected is set so that a range of a distance from the rib waveguide to the area to which the metal electrode is connected is such that when the distance is changed, an effective refractive index of the rib waveguide in a zeroth-order mode does not change.

摘要： Optical guided mode fast 1×2 and 2×2 spatial switches are provided that can be used in multimedia communication networks. These switches require a relative refractive index change of only 0.0001˜0.0002 and can be realized using Lithium Niobate, Polymers, semiconductors, etc. Extinction ratios of these switches are made to be better than 45 dB, by introductions of a rear edge adjusted broken electrode and a blocker electrode into their architecture. Optical losses are less than 3 dB, and excellent switching characteristics are achieved by suppressing cross talk to ˜50 dB. The two output ports of the 1×2 (2×2) switch are made to be spatially perpendicular (in opposition) by introduction of air grooves, allowing for two-dimensional integration of unit switches into matrices. System applications of the switch are made flexible due to a discrete drive requirement for each optical input to the 2×2 switch.
