摘要： An all-optical, self-aligning, holographic phase modulation and motion sensing apparatus includes a crystal exhibiting a zero electric field photorefractive effect, a phase modulation or vibration source or mechanism, a source of coherent optical radiation, beam splitting and directing optics, and at least one optical radiation detector. The output from the optical radiation source is split into separate beams, one or all of which are phase modulated. The beams are directed through the crystal exhibiting a zero electric field photorefractive effect, and the resultant transmitted beams are detected by an optical radiation detector to provide a measurement of the phase modulation of the beams. The sensor functions in the absence of an electric field because of the unique characteristic of the crystal exhibiting the zero electric field photorefractive effect whereby if either the phase of the crystal's index grating or of the interfering beams is modulated with a phase change very much less than .pi./2, the intensity of the beam transmitted through the crystal varies linearly with the modulation. Such linear modulation allows crystals exhibiting the zero electric field photorefractive effect to remotely sense phase modulations or vibrations of any type in the absence of electrical signals in the vicinity of the sensor.

摘要： The principles of the present invention relate to aligning optical components with three degrees of translational freedom. A lens pin, a lens base, and a molded package are aligned in a first direction, a second direction, and a third direction such that the signal strength of optical signals transferred between a lens included in the lens pin and the molded package is optimized. The lens pin is mechanically coupled to the lens base to fix the position of the lens relative to the molded package in the first direction. Subsequently, the lens base and the molded package are realigned in the second and third directions such that the signal strength is again optimized. The lens base is mechanically coupled to the molded package to fix the position of the lens base relative to the molded package in the second and third directions.

摘要： Methods and processes are disclosed for calibrating optoelectronic devices, such as optoelectronic transceivers and optoelectronic receivers, based upon a measured avalanche photodiode bit error rate. In general, the method involves measuring a bit error rate for the avalanche photodiode and adjusting the reverse bias voltage of the avalanche photodiode until the bit error rate is minimized. This process is repeated for each of a variety of different thermal conditions. Information concerning each thermal condition and the corresponding reverse bias voltage is stored in a memory of the optoelectronic device.
