摘要： A method and an electro-optical device are presented for affecting the propagation of input light impinging on the device. The electro-optical device is composed of at least one domain-patterned ferroelectric crystal structure with inverted domains, and an electrodes' arrangement on the surface of the at least one structure connected to a voltage source. When the input light is appropriately directed onto the electro-optical device, and voltage is appropriately applied to the electrodes, this causes at least one of the following effects: deflecting a light component of a predetermined wavelengths contained in the input light from the direction of propagation of the input light so as to direct this light component in a reflection output direction, while allowing the other light components to propagate in the direction of propagation of the input light; changing the phase of the input light in a wavelength-dependent manner; and separately controlling the wavelength-dependent transmission and dispersion for different polarizations of light.

摘要： An optical fiber system that enables direct board-to-board optical communication is described. The optical fiber system does not require data transmission through the backplane and, consequently, avoids the complexity and possible communication delays that would be required if data transmissions had to go through the backplane. The optical fiber system includes a positioner that is configured to urge opposite ends of two or more optical fibers respectively toward opposed optical devices that are coupled to facing sides of adjacent printed circuit boards coupled to a common backplane. The optical fiber system may be installed and removed quickly and easily, and may be readily retrofitted into existing computer systems.

摘要： Methods for fabricating a non-linear optical (NLO) film and a NLO film structure produced thereby are provided. The methods include depositing an alignment layer material on at least one surface of a substrate, aligning the molecules of the alignment layer material in a substantially uniaxial direction, and depositing a NLO film on the alignment layer material. The methods may be advantageous in that they tend to produce NLO films having relatively strong NLO properties. The methods may be further advantageous in that they are relatively simple and may be applied to a wide range of organic NLO materials.

摘要： A fiber optic projection device is provided that includes red, green and blue fiber optic sources, each of which includes at least one fiber amplifier for emitting an amplified signal of a predetermined wavelength. To provide signals that are scalable to high power levels, each fiber optic source can include a master oscillator, a plurality of fiber amplifiers for amplifying the input signals provided by the master oscillator and a combiner for combining the amplified signals emitted by each of the fiber amplifiers. While the fiber amplifier of each fiber optic source can be a dual core fiber that is appropriately doped, the red fiber optic source can include fiber amplifiers that rely upon Raman gain to provide the desired amplification. The red fiber optic source therefore not only includes a master oscillator, but also includes a red subharmonic oscillator for generating signals having a Raman seed wavelength for amplification by the fiber amplifiers. Each fiber optic source also includes a frequency altering device, such as a frequency doubler, for altering the frequency of the amplified signals to produce a signal having the respective color. The fiber optic projection device also includes at least one modulator for individually modulating the intensity of the signals having the respective colors. For example, the master oscillator can be modulated to control the duty cycle of the emitted signals. Further, the fiber optic projection device can include a projector for mixing the modulated signals having the different colors to create a full color image.

The second compartment is proximate the first compartment. In FTTH applications, the second compartment stores at least one coupler tray that splits a first optical fiber of the fiber optic feeder cable into a plurality of second optical fibers. In FTTC applications, the second compartment receives express optical fibers of the fiber optic feeder cable. The third compartment extends in a lengthwise direction alongside the second compartment and stores slack. lengths of the optical fibers of the drop cable. The fourth compartment is proximate the third compartment and is adapted to store at least one of a splice tray or a connector panel, or both. The fourth compartment interconnects an optical fiber of the fiber optic feeder cable, such as one of the second optical fibers provided by the coupler tray, to a respective optical fiber of a drop cable.

摘要： Between a lens of a collimator and a retro-reflector as a total reflecting element, a prism, a polarizer, a Faraday rotator and a linear retarder are arranged in the order. The core/clad section serving as an input optical fiber of the collimator has its optical axis coincident with an optical axis of the lens. When the light exited the collimator reaches the retro-reflector, the outgoing light reflects deviated by a spacing Y, the returning light of which is refracted by the prism and incident on the core/clad serving as an output optical fiber of the collimator.

摘要： The present invention, generally speaking, provides compact design of optical couplers for combining two differently polarized light beams onto a collimator or splitting a composed light beam into two differently polarized light beams. According to another embodiment, the size of the polarization beam combiner is minimized by using a pair of specially designed fiber collimators that use an asymmetrical sleeve. As a result, a coupler, according to the present invention, uses less components, is of small in size and provides an easy-aligning structure. Further the coupler offers lower optical insertion loss with minimized physical size.

摘要： An optical isolator includes a first optical collimator, a first birefringent crystal, a Faraday rotator, a second birefringent crystal and a second optical collimator. The first and second collimators have the same structure and configuration. Each first and second collimator includes a ferrule, an optical fiber retained in the ferrule, and a collimating lens, all of which are secured in a tube. The first and second birefringent crystals are respectively fixed to the first and the second collimators. The Faraday rotator is stationed between the first and second collimators, and fixed onto an end of the first collimator. In assembly, the first and second collimators and the Faraday rotator are all secured in a stainless steel outer tube. The second collimator is rotated within the outer tube until correct relative alignment of optical axes of the birefringent crystals is attained.
