摘要： The present invention provides an apparatus and method for high-density optical wavelength division multiplexing (WDM) using a single optical source. An optical wavelength division multiplexer in accordance with the present invention includes an optical source providing an optical pulse signal. A wavelength splitter separates the optical pulse signal spectrum into a plurality of channel signals at different wavelengths such that each channel signal may be separately modulated or otherwise processed. A wavelength combiner then recombines the separately modulated channel signals to provide a high-density WDM optical signal particularly well-suited for use in optical circuit interconnection and optical communication network applications. The high-density single-source multiplexer of the present invention may also be conveniently adjusted to align channel signal wavelengths or to compensate for optical fiber dispersion.

摘要： A network for multi-bit word parallel communication between optoelectronic chips on a two dimensional array of optical input and output channels carried on a single dimension of optical fibers. Each bit of a word is carried on a different wavelength and the multiple wavelengths carrying a word are wavelength multiplexed onto a single optical fiber. Multiple fibers can be joined into a one dimensional array of fibers. A transceiver for transmitting and receiving along the optical data channels comprises an array of modulators powered by individual wavelength light beams, either from individual monochromatic light sources and a light beam from a single broadband light source made to pass through a diffraction grating. The modulators are positioned so that each modulator reflects a different wavelength light beam, thereby providing multiple optical channels. Alternatively, multiple wavelengths are generated from CMOS integrated light sources. These multiple optical channels are then collimated and guided into one single mode fiber or multiple multimode fibers at its transmitting end. At the receiving end a diffraction grating is used to separate the distinct data channels by their individual wavelengths. The multiple wavelengths are then caused to fall on an array of optical detectors spaced according to the individual wavelengths to be detected. By constructing a one dimensional array of these fibers, a two dimensional array of optical data channels is realized. The size of the array is determined by the number of fibers and the number of distinct wavelengths combined in each fiber.

摘要： An electrooptic measuring apparatus having both high voltage sensitivity and femtosecond time resolution includes coplanar transmission lines fabricated on a semi-insulating multiple quantum well structure. An electrical signal, such as from a high speed electronic device, injected onto the transmission lines creates an electrical field parallel to the layer planes of the multiple quantum well structure. Excitonic electroabsorption by the multiple quantum well structure, in response to the parallel field, changes the transmissivity of the multiple quantum well structure. An external light beam directed through the multiple quantum well structure is modulated by the changes in transmissivity. By detecting this modulation, a sampling of the electrical signal is achieved.

摘要： Described refractive correctors, include, but are not limited to, intraocular lenses (IOLs), contact lenses, corneal inlays, and other optical components or devices, incorporating a continuous central phase zone and peripheral phase discontinuities. Further embodiments are directed to a method for using a laser to modify the refractive properties of refractive correctors to form such continuous central phase zone and peripheral phase discontinuities, and other applications. The refractive corrector and methods adapt a Fresnel lens structure to include continuous phase retarding regions having a wavefront height of greater than one design wavelength in a central zone of a refractive corrector to improve human vision applications, while maintaining benefits of phase wrapping in the peripheral region.

摘要： By adapting femtosecond micromachining approaches developed in hydrogels, we can perform Intra-tissue Refractive Index Shaping (IRIS) in biological tissues. We reduced femtosecond laser pulse energies below the optical breakdown thresholds to create grating patterns that are associated with a change in the refractive index of the tissue. To increase two-photon absorption, we used a two (or more)-photon-absorbing chromophore.

摘要： A method for modifying a refractive property of ocular tissue in an eye by creating at least one optically-modified gradient index (GRIN) layer in the corneal stroma and/or the crystalline by continuously scanning a continuous stream of laser pulses having a focal volume from a laser having a known average power along a continuous line having a smoothly changing refractive index within the tissue, and varying either or both of the scan speed and the laser average power during the scan. The method may further involve determining a desired vision correction adjustment, and determining a position, number, and design parameters of gradient index (GRIN) layers to be created within the ocular tissue to provide the desired vision correction.

摘要： A method for providing vision correction to a patient. The method includes: (a) measuring the degree of vision correction needed by the patient and determining the location and shape of refractive structures that need to be positioned within the cornea to partially correct a patient's vision; (b) directing and focusing femtosecond laser pulses in the blue spectral region within the cornea at an intensity high enough to change the refractive index of the cornea within a focal region, but not high enough to damage the cornea or to affect cornea tissue outside of the focal region; and (c) scanning the laser pulses across a volume of the cornea or the lens to provide the focal region with refractive structures in the cornea or the lens. Again, the refractive structures are characterized by a change in refractive index, and exhibit little or no scattering loss.
