Abstract: An optical fiber cable and magnetic field detector magnetostrictively reave to the presence of an external magnetic field is presented, and methods thereof. The optical fiber cable comprises a elongated optically transparent core sheathed by a magnetostrictively responsive jacket disposed about the periphery of the core. The jacket responds to magnetic fields present and strains the core effecting the light transmission of the core. The effect upon the light transmission by the jacket is detected by interferometry for determining the presence of the magnetic field.

Abstract: A wavelength selective optical fiber coupler having various applications in the field of optical communications is disclosed. The coupler is composed of dissimilar waveguides in close proximity. A light induced, permanent index of refraction grating is recorded in the coupler waist The grating filters and transfers energy within a particular range of wavelengths from a first waveguide to a second waveguide. Transversely asymmetric gratings provide an efficient means of energy transfer. The coupler can be used to combine or multiplex a plurality of lasers operating at slightly different wavelengths into a single fiber. Other embodiments such as a dispersion compensator and gain flattening filter are disclosed.

Abstract: A fully parallel CCD memory chip of N address lines which detects in just one clock cycle, a perfect match between an input pattern and any of a plurality of stored patterns and also detects in less than (N+1)-comparison cycles and still just one XOR operation, the best matching in case a perfect one does not exist. The chip disclosed herein has a fully parallel architecture in which an input word is compared to all stored words at one time. A preferred embodiment of the invention uses a four phase CCD, wherein each stored word occupies one row of the CCD and each such bit of each such word occupies two cells. Where perfect matches exist, only one comparison clock cycle is needed to compare the input word with all stored words and where there is no perfect match, the best match will be detected on a subsequent comparison pulse. Charge packets represent binary words generated by external pulses that are applied to the chip through data input lines and then are compared to the data applied to the address lines. The sensing is done directly on the cells in a non-destructive sensing process in parallel, rather than at the end of each row.

Abstract: 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.

Abstract: An adjustable CCD gate structure utilizing ultra-violet light activated floating gates, wherein a floating polysilicon gate is used between a CCD electrode and the underlying substrate to provide a fixed voltage bias to the CCD gate during the manufacturing process thereof The floating gate is programmed with a desired voltage bias during the application of ultra-violet light and is thereafter fixed at that adjusted level, upon the removal of the ultra-violet light. Thus, the method of the present invention comprises the steps of providing a CCD gate structure in which there is such a floating polysilicon gate between the CCD electrode and the underlying substrate; applying an ultra-violet light activation to the floating polysilicon gate; applying a voltage to the conventional CCD electrode which is resistively coupled to the floating electrode for adjusting the bias on the floating electrode to a desired level; and then removing the ultra-violet light to fix the voltage bias at the floating polysilicon gate at a permanant level.
