    摘要： An optical mode coupling apparatus includes an Erbium-doped optical waveguide in which an optical signal at a signal wavelength propagates in a first spatial propagation mode and a second spatial propagation mode of the waveguide. The optical signal propagating in the waveguide has a beat length. The coupling apparatus includes a pump source of perturbational light signal at a perturbational wavelength that propagates in the waveguide in the first spatial propagation mode. The perturbational signal has a sufficient intensity distribution in the waveguide that it causes a perturbation of the effective refractive index of the first spatial propagation mode of the waveguide in accordance with the optical Kerr effect. The perturbation of the effective refractive index of the first spatial propagation mode of the optical waveguide causes a change in the differential phase delay in the optical signal propagating in the first and second spatial propagation modes. The change in the differential phase delay is detected as a change in the intensity distribution between two lobes of the optical intensity distribution pattern of an output signal. The perturbational light signal can be selectively enabled and disabled to selectively change the intensity distribution in the two lobes of the optical intensity distribution pattern.

    摘要： An integrated semiconductor device which forms an optoelectronic switch and includes: a directional coupler structure in which one of the guides receives the input light power and the other guide is formed by multiple quantum wells, which structure is so dimensioned that in the zero-bias state the switch is in the crossover state, and switching control means.The structure includes layers which form at least one PIN structure in which the waveguide consisting of multiple quantum wells constitutes an intrinsic region I, and the control means include means for reverse-biasing of the PIN structure which supplies the negative feedback so that switching from one state to the other is initiated by a change in the level of the luminous power injected into the input waveguide.

    摘要： A nanophotonic device includes at least two waveguides located on top of a transparent substrate, which form an intersection point at which a part of a first waveguide simultaneously constitutes a part of a second waveguide. A nanoscale element located on top of the intersection point so that it partially or completely covers the intersection point is switchable between two different states, which differ by a refractive index value. The nanophotonic device is operated by injecting at least two optical pulses into the waveguides. Intensity of the optical pulses is selected so that a superposition of the optical pulses switches the nanoscale element into a desired state. Also disclosed is a nanophotonic matrix array in which parallel waveguides form nanophotonic devices. The nanophotonic matrix array may be used as a spatial light modulator (SLM), as an optical mirror, as an optical absorber, or as a tunable optical grating array.
