摘要： A method is for aligning an electro-optic device. The method may include initially positioning an optical fiber array adjacent to optical grating couplers, and actively aligning the optical fiber array relative to the optical grating couplers in a yaw direction and a roll direction to determine a yaw and roll alignment at a first operating wavelength. The method may include actively aligning the optical fiber array relative to optical grating couplers in an x direction and a y direction to determine a first x and y alignment at the first operating wavelength, determining a second operating wavelength, and actively aligning the optical fiber array again relative to the optical grating couplers in the x direction and y direction to determine a second x and y alignment at the second operating wavelength.

摘要： Aspects of the disclosure are directed to optical microcavities and emitters that are spectrally aligned in an arrangement having an array of such microcavity-emitter combinations. The spectral alignment can be selective, in that a portion of the array of microcavity-emitter combinations, or a single microcavity-emitter combination, can be individually spectrally aligned. In specific examples, light is coupled within a semiconductor device having wavelength-dependent structures and optical cavities optically couple to the wavelength-dependent structures. One of the optical cavities and a wavelength-dependent structure are spectrally aligned, independent of another of the optical cavities.

摘要： A real-time, optoelectronic (OE) alignment system, including a first OE device and a second OE device optically coupled to the first OE device, is disclosed. In an exemplary embodiment of the invention, the alignment system includes a capturing means for maintaining the second OE device in a fixed position. The capturing means further retains the first OE device in optical engagement with the second OE device, with the first OE device further having a plurality of degrees of positional freedom associated therewith. An error detection means generates a positional error signal whenever either of the first and second OE devices has deviated from a desired optical alignment with respect to the other. In addition, an actuation means, responsive to the error detection means, automatically adjusts the position of the first OE device so as to bring said first OE device in the desired optical alignment with said second OE device.

摘要： A positioning system for selectively directing a first beam of light towards a destination and a second beam of light towards a first diffractive optic. The first beam of light and the second beam of light traverse a substantially co-linear optical path. The first diffractive optic diffracts the second beam of light into a plurality of optical spots. The second beam of light comprising the plurality of optical spots is directed onto a second diffractive optic. A change in position of the plurality of optical spots relative to the second diffractive optic is sensed in a reflection of the second beam of light by a detection element and representative signals are derived thereof. The signals are coupled to a directing assembly, which directs the first beam of light towards the destination.

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.
