摘要： The purpose of the present invention is to provide an optical member and the like which enable suppression of diffusion of stray light due to a pigment even when the optical member and the like are used adjacent to a light guiding part through which incident light is transmitted. The optical member is configured to be used adjacent to the light guiding part through which the incident light is transmitted and to attenuate the incident light. The optical member has a dispersed carbon particle part that is formed as a result of dispersion of carbon particles in a particular region in a silicone resin. The carbon particles are stray light diffusion suppressing particles for suppressing the intensity of light being incident onto the carbon particles and diffused.

摘要： Various embodiments include large cores fibers that can propagate few modes or a single mode while introducing loss to higher order modes. Some of these fibers are holey fibers that comprise cladding features such as air-holes. Additional embodiments described herein include holey rods. The rods and fibers may be used in many optical systems including optical amplification systems, lasers, short pulse generators, Q-switched lasers, etc. and may be used for example for micromachining.

摘要： A luminescent photonic structure that comprises a luminescent material that when excited by an excitation light having a wavelength within an excitation wavelength spectrum of the luminescent material emits luminescent light having a luminescence wavelength spectrum. The luminescent photonic structure comprises a photonic crystal disposed between two other photonic crystals. The photonic crystal has a photonic lattice period within one of the luminescence wavelength spectrum and the excitation wavelength spectrum. The two other photonic crystals each have a photonic lattice period within the other of the luminescence wavelength spectrum and the excitation wavelength spectrum for reflecting one of excitation light and luminescent light propagating within the photonic crystal.

摘要： An optical attenuator and/or optical terminator is provided. The device includes an optical channel having two regions with different optical properties, such as an undoped silicon region which is less optically absorptive and a doped silicon region which is more optically absorptive. Other materials may also be used. A facet at the interface between the two regions is oriented at a non-perpendicular angle relative to a longitudinal axis of the channel. The angle can be configured to mitigate back reflection. Multiple facets may be included between different pairs of regions. The device may further include curved and/or tapers to further facilitate attenuation and/or optical termination.

摘要： One example includes an optical coupler. The optical coupler includes a waveguide formed in a first layer of a layered structure that is to propagate an optical signal. The waveguide includes an end portion. The optical coupler also includes a turning mirror that includes a bulk structure and a reflective material deposited on an angular face of the bulk structure to form a surface of the turning mirror. The bulk structure can have a greater cross-sectional size than a cross-sectional size of the waveguide, such that the angular face extends above the first layer of the layered structure and extends into a second layer of the layered structure below the first layer. The surface of the turning mirror can be arranged to reflect the optical signal that is provided from the end portion of the waveguide.

摘要： The objective of the present invention is to provide an optical modulator adapted for use with various modulating units and various modulation regions, and with which variability in optical losses is limited as far as possible. An optical modulator in which an optical waveguide and a control electrode for controlling an optical wave propagating through the optical waveguide are provided in a substrate, characterized in that: the optical waveguide is provided with a first branching portion which causes one input light beam to branch into two light beams; each of a first and a second modulating portion connected to two branched waveguides which branch at the first branching portion is provided with a structure in which one or more Mach-Zehnder type optical waveguides are combined; the control electrode comprises signal electrodes which apply modulated signals to the first and second modulating portions; input portions of all the signal electrodes are disposed on either the left or the right of the substrate relative to the direction in which the optical wave propagates; and in relation to output portions of the signal electrodes, the output portions of the signal electrodes led out from each modulating portion are disposed on the side on which the first or second modulating portions are disposed, relative to the direction in which the optical wave propagates.

摘要： Exemplary apparatus for method for forming at least one spectral encoding endoscopy configuration. For example, it is possible to modify a spacer configuration and an lens optics configuration to have respective predetermined lengths, and also to modify a dispersive optics configuration to have a further predetermined length. Further, the modified spacer and modified lens optics configurations can be attached to one another to form a combined spacer-lens optics configuration. The modified dispersive optics configuration can be attached to a substrate to form to form a grating substrate configuration. Additionally, the combined spacer-lens optics configuration can be connected to an optical fiber, and the modified attached dispersed optics configuration can be connected to the modified attached lens optics configuration to form the spectral encoding endoscopy configuration(s) which can extends along a particular axis. The dispersive optics configuration can be modified to be at a predetermined angle with respect to the particular axis.
