摘要： A polarization-independent optical multiplexer/demultiplexer with wide passbands has a core including an input optical waveguide, an input slab optical waveguide connected to the input optical waveguide, a waveguide array connected to the input slab optical waveguide, an output slab optical waveguide connected to the waveguide array, a pair of multimode couplers connected to the output slab optical waveguide, and a pair of output optical waveguides connected to the multimode couplers. The multimode couplers are dimensioned so that as both TE and TM polarized light propagates through them, the phase difference between the fundamental and second-order modes changes by an odd multiple of pi radians.

摘要： An optical device has two optical waveguides embedded in a clad. The optical waveguides are mutually parallel and are separated by a distance that allows optical coupling between them. The optical waveguides have identical square cross sectional shapes in a plane orthogonal to the direction of light propagation, so that light propagates through each optical waveguide without polarization dependence. The length of each side of the square cross section of the optical waveguides is determined from the refractive index of the clad and the distance between the longitudinal axes of the optical waveguides so that coupling between the two optical waveguides is also polarization independent for light with a wavelength of 1.49 micrometers, which is the longer of the two wavelengths used in optical subscriber networks.

摘要： A projector projects an image onto an image projection area by scanning the image projection area with a light beam including both image signal light and communication signal light. The image signal light and communication signal light may have different wavelengths, or the communication signal may be modulated onto one or more of the wavelengths of the image signal light. A terminal receives the communication signal light from the image projection area, processes the communication signal, and when necessary, transmits an answering signal to the projector. An audience equipped with such terminals can interact with the projected image at a high data communication rate without impairing the visibility of the image.

摘要： The present invention expands a selective wavelength band and flattens light intensity in the selective wavelength band as good as or better than prior art, and makes power loss less than prior art. The invention as a period characteristic wavelength splitter and an arrayed waveguide diffraction grating wavelength splitter between the first input/output port and the second input/output port in this sequence. The period characteristic wavelength splitter is comprised of the third star coupler, the second arrayed waveguide comprised of multiple waveguides having different optical path lengths, and the fourth star coupler. When an optical signal is input from the first input/output port, the period characteristic wavelength splitter outputs optical signals which wavelengths sequentially deviated with difference &dgr; from multiple ports at the first star coupler side of the fourth star coupler. The optical signals which can be output from the multiple ports are all periodic optical signals with waveform difference &Dgr;&lgr;for any one of the ports.

摘要： A wavelength conversion apparatus has an optical amplifier, a wavelength converter, and an optical coupler coupled to form an optical ring resonator. The optical amplifier supplies pump light. The wavelength converter generates converted light, either from the pump light alone or by interaction between the pump light and signal light supplied from a signal source. The optical coupler extracts the converted light. The optical ring resonator preferably includes a tunable optical bandpass filter that defines the wavelength of the pump light. The optical coupler may also couple the signal light into the optical ring resonator, preferably through a polarization beam splitter and at least one polarization rotator, making the apparatus insensitive to the polarization of the signal light.

摘要： A photonic switching method and a photonic switch utilizing the method are disclosed. Input electrical signals Ea.about.Ed are input through plural input ports 21a.about.21d are converted into optical signals with the pulse intervals of these input electrical signals being preserved unchanged. The converted optical signals are timing adjusted within the pulse interval and multiplexed in such a manner that these optical signals do not overlap with each other on the time axis. The resulting multiplexed optical signals are transferred to output ports 19a.about.19d. An optical signal, from among the multiplexed optical signals, which should be output at a target output port is separated by utilizing a mutual optical interactional function, for example, a four optical wave mixture.
