摘要： In a method or system for interrogating an optical chip (50), the optical chip (50) is illuminated with input light (30) and a spatially resolved image (50i) of the output light (31,32) is measured from the optical chip (50). The output light (31,32) is imaged together with a reflection of the input light (30). For example, this can be used to establish, improve, or maintain alignment of the input light (30) on a sensor input port (51) of the optical chip (50). The same detector (17) measures the spatially resolved image and a spectral response of the optical chip (50).

摘要： A system for injection of a useful radiation beam into an optical fiber is disclosed including a secondary radiation source, which is connected to the optical fiber such that a secondary radiation beam leaves by an end of the optical fiber. A variable deviation device, for deviating the useful radiation beam towards the end of the optical fiber, an optical detection assembly, identifying the direction of the secondary radiation beam, and an injection controller, for controlling the variable deviation device depending on the direction of the secondary radiation beam. The secondary radiation may be made up by an amplified spontaneous emission from a laser amplifier which is used for amplifying the useful radiation. The injection system may advantageously be used in a terminal for optical telecommunication by laser signals.

摘要： A method of processing an optical fiber having a first facet and a second facet is provided. The method includes the steps of applying a photosensitive material to a region on the first facet at least including an entirety of a core in a generally uniform thickness, irradiating light of a predetermined wavelength from the second facet through an inside of the optical fiber, with the first facet dipped in a predetermined solution that has generally the same refractive index as that of the photosensitive material, so as to expose only the photosensitive material applied to the core in the first facet, and forming a level gap at a boundary between a core facet and a clad facet in the first facet, at least after the first facet lifted out of the solution undergoes development.

摘要： An optical communication device includes a light source that emits a light beam and an optical fiber having a core and a cladding. The optical fiber has a light entrance face having a core region and a cladding region. The light beam emitted by the light source is converged by a converging lens on the core region and is transmitted through the optical fiber. The entrance face is configured to generate a light intensity distribution in light reflected by the light entrance face depending on a position where the light beam is incident on the entrance face, a converging lens arranged between the light source and the optical fiber.

摘要： An optical communication device includes a light source that emits a light beam for transmitting data, and an optical fiber that has an entrance face through which the light beam emitted from the light source enters the optical fiber. The entrance face has a core region and a cladding region. A beam spot moving mechanism moves a beam spot formed by the light beam emitted from the light source on the entrance face of the optical fiber in first and second directions. A light detector having a light receiving surface detects light amount of the light beam reflected by the entrance face of the optical fiber. The light receiving surface is divided in multiple light detecting areas. A controller controls the beam spot moving mechanism to adjust light amounts detected by the light detecting areas to a predetermined ratio. For example, the controller controls the beam spot moving mechanism so that the light amounts detected by the light detecting areas become the same.

摘要： A vehicle lighting system includes one or more central light sources, a plurality of optical loads including headlight lenses, an optical fiber network that extends from the light sources to illuminate the headlight lenses and other optical loads, and optical switches and oscillators that include respective input fibers illuminated from the light source and output fibers to respective optical loads, and operate by enabling and disabling optical connections between their input and output fibers. The headlight assemblies switch between high and low beams by moving their fibers vertically, and control beam diffusion by moving the fibers parallel to the lens axes, including an automatic diffusion adjustment for a headlight reflection from a vehicle in front. The switches include various mechanisms for moving the input and output fibers into and out of alignment with each other, including a shaped resilient sleeve, a hinge pivotally joining the fibers, an opaque shutter with a transmissive section movable between the fibers, and also a liquid-based switch that relies upon total internal reflection. A feedback mechanism for some of the switches dims the source lamp when the switch is OFF to conserve energy. The oscillators operate by normally urging an input fiber towards an OFF position, at which it actuates a mechanism that shifts it to an ON position at which the mechanism is deactivated. A failsafe system employs multiple light sources, with each source sharing its light output with the load for another source that has failed.
