摘要： A surface (17d') facing a photoelectric conversion apparatus is formed on the optical block (3) side, said surface having light from a light emitting element (10) inputted thereto and monitor light outputted therefrom, and a coupling light output surface (12) having coupling light outputted therefrom is formed on the optical housing (4) side, and consequently, the surface (17d') and the coupling light output surface (12) are simply and highly accurately formed. Then, an optical block (3) and an optical housing (4) are simply and accurately combined by being fitted together by means of fitting sections (21, 24). Adhesion of foreign materials and formation of scratches on the reflecting surface (18) of the optical block (3) are suppressed by covering the reflecting surface (18) with the optical housing (4).

摘要： A space active optical cable (SAOC) includes a cable including one or more optical fibers, and two or more electrical transceivers on opposing ends of the cable and interconnected by the cable. Each of the electrical transceivers includes an enclosure that encloses one or more light sources, one or more light detectors, and control electronics. Also included in the enclosure are a coupling medium to couple light into and out of the one or more optical fibers. The coupling medium can be reflecting surface or an on-axis mount. The enclosure provides a suitable heat propagation and electromagnetic interference (EMI) shielding, and the cable and the two or more electrical transceivers are radiation resistant. SAOC features optionally support a health check algorithm that allows trending optical performance in the absence of an optical connector and a potential surface treatment to increase nominally low emissivity of an EMI conductive surface.

摘要： A method for determining receiver coupling efficiency includes varying optical power inputted into a half active optical cable to determine a maximum optical power at which the TIA squelches and determining a receiver coupling efficiency by calculating a ratio of a threshold optical power to the maximum optical power at which the TIA squelches. A method of determining link loss in a channel includes varying optical power of a light source to determine the maximum optical power at which the TIA squelches and determining the link loss in the channel by subtracting the maximum optical power from the threshold optical power. A method of determining link topology includes selecting a pattern of optical powers and matching a pattern of squelched and non-squelched outputs with the pattern of optical power. An active optical cable includes memory storing a value related to an initial link loss of the active optical cable.

摘要： An optical waveguide device is provided which can efficiently guide undesired light to the outside of a substrate or the outside of the overall optical waveguides even when optical waveguides are integrated. In the optical waveguide device, an optical waveguide is formed on a substrate, the optical waveguide includes a main waveguide in which signal light propagates and an undesired-light waveguide for removing undesired light from the main waveguide, and the undesired-light waveguide is separated by the main waveguide interposed therebetween at an intersection in which the undesired-light waveguide and the main waveguide intersect each other.

摘要： Embodiments of the present invention provide an optical assembly and an optical module, where the optical assembly includes a main body and a total reflection device, where the main body includes a fiber connection portion and a light processing portion, where the fiber connection portion is connected to the light processing portion, the fiber connection portion is connected to an external fiber, and a light splitting surface is disposed in the light processing portion, configured to reflect a part of incident rays to an MPD, and transmit the other part of the incident rays; and the total reflection device is disposed in the light processing portion, configured to reflect, to the fiber connected to the fiber connection portion, the incident rays transmitted by the light splitting surface. The light splitting surface is disposed to directly reflect a part of incident rays to the MPD for testing. In this way, an optical path is relatively short, and package can be performed by means of a COB, thereby decreasing a size of the optical assembly, and implementing miniaturization of the optical module to which the optical assembly is applied.

摘要： Disclosed are a filter, a method for producing a filter, and a laser wavelength monitoring apparatus, where the filter includes: two translucent bodies, where each of the translucent bodies has a first plane, a second plane that forms a wedge angle with the first plane, and a third plane that intersects with both the first plane and the second plane, first planes of the two translucent bodies are parallel to each other, and second planes of the two translucent bodies are parallel to each other; a beam splitting film, where surfaces of both sides are respectively combined with the first planes of the two translucent bodies; and two reflective films, respectively combined with the second planes of the two translucent bodies. A wavelength monitoring optical path of the laser wavelength monitoring apparatus in the solutions is significantly shortened compared with that in the prior art, a volume of the laser wavelength monitoring apparatus is relatively small, and miniaturized packaging can be implemented, which significantly reduces packaging costs of a product. In addition, monitoring precision is relatively high.
