    摘要： A fiber optical Y-junction device includes a l.times.N optical fiber coupler connected to N fiber optic amplifier module structures constructed from a doped optical fiber. When the optical Y-junction structure contains a fiber optic amplifier, the fiber optical Y-junction device is operable as either a modulator or lossless power divider. A nonblocking optical switch is constructed by coupling M.times.l optical fiber couplers to the outputs of the fiber optic amplifier module structures utilizing the fiber optical Y-junction.

    摘要： An optical communication system having nodes that include add/drop units. The add/drop unit includes: a network input port for receiving optical energy having a plurality of different wavelengths from other nodes in the network; a network output port for coupling to destination nodes in the network; an add port for receiving optical energy having the plurality of different wavelengths from a local source for transmission to other nodes in the network; and a drop node for receiving optical energy from other nodes in the network for local processing. A wavelength demultiplexer is included to separate the plurality of wavelengths received by the network input port so that the electronically controllable beam steerer can process them individually. A wavelength multiplexer is included to combine the plurality of wavelengths received from the electronically controlled beam steerer for delivery to the network output port for transmission to other nodes in the network. An electronically controllable beam steerer is provided for receiving the optical energy having the plurality of different wavelengths at the network input port and the optical energy having the plurality of different wavelengths from the add port for selectively: directing the optical energy having the plurality of different wavelengths at the network input port to the network output port or to the drop port; and directing the optical energy having the plurality of different wavelengths from the add port to the network output port. The disclosed add/drop unit supports one or a plurality of add, input, output, and drop ports.

    摘要： A fiber optic amplifier is disclosed utilizing a doped fiber to provide amplification through stimulated emission. The doped fiber is simultaneously pumped by multiple pump lasers generating optical waves of differing wavelengths. The optical waves from the lasers are combined using a wavelength division multiplexer before introduction into the doped fiber. The use of multiple pump lasers decreases the power requirements of each laser, reduces the cost of the amplifier, and increases reliability without compromising the gain of the amplifier.

    摘要： Apparatus employing a light beam to affect another light beam. A primary beam of linearly polarized monochromatic light is directed on an element of chromium chalcogenide spinel magnetic semiconductor, specifically single crystal CdCr.sub.2 Se.sub.4. A control beam of monochromatic light is selectively elliptically polarized and directed at the element. As the light beams traverse the same path through the element the circularly polarized control beam interacts with the element thereby changing the effect of the element on the linearly polarized primary beam to rotate the plane of linear polarization of the primary beam. A linear polarization analyzer receives the primary beam from the element and passes, blocks, or diverts light depending upon the plane of linear polarization of the incident light.
