摘要： A fiberoptic coupler capable of many functions is presented. The basic fiberoptic coupler has a first sleeve, a second sleeve, a first collimating GRIN or conventional lens, and a second collimating GRIN or conventional lens. The first sleeve holds end sections of two or more input optical fibers along the longitudinal axis of the sleeve. The second sleeve holds an end section of at least one output optical fiber. The end face of the second sleeve faces the first sleeve end face. The first collimating GRIN or conventional lens in front of the first sleeve end face collimates light signals from the input optical fibers and the second collimating GRIN or conventional lens in front of the second sleeve end face focusses light signals from at least one of the input optical fibers into the single output fiber, or at least one of the output optical fibers. With only one output fiber the coupler operates as a combiner. If more than one output fiber is held by the second sleeve, the input and output fibers can be arranged so that a light signal from one input fiber is sent to one output fiber. For added functionality, optical elements, such as isolators and wavelength-dependent filters, ca be inserted between the first and second collimating lenses.

摘要： A fiberoptic network transmission system combines the output signals of several laser sources into a single optical fiber. The transmission system has integrated optical isolator couplers which each have at least two input optical fibers and an output optical fiber. Each input optical fiber is connected to a laser source and the output optical fiber is connected to an input terminal of a combiner which has its output terminal connected to the single optical fiber. The integrated optical isolator couplers block light from the single optical fiber from reaching any of the laser sources.

摘要： A fiberoptic amplifier system having an optical amplifier, which receives an input signal and generates an amplified signal and amplified spontaneous emission noise, and a variable polarization beam splitter, which receives the amplified signal and amplified spontaneous emission noise from the optical amplifier. The amplified spontaneous emission (ASE) noise is a broadband optical noise with a random polarization state in a rare earth-doped fiber optical amplifier. In a semiconductor laser diode optical amplifier, the ASE noise is partially polarized depending upon the waveguide structure of the laser diode. In the rare earth-doped fiber optical amplifier noise figure reduction configuration, the variable polarization beam splitter is responsive to the polarization of the amplified input signal to split one-half of the amplified spontaneous emission noise away from the amplified input signal and remaining one-half of the amplified spontaneous emission noise into a first port and the amplified input signal and the remaining one-half of the amplified spontaneous emission noise passes to an output port. This significantly reduces the noise figure of the fiberoptic amplifier system.

摘要： The present invention provides an improved clip for supporting an end of an optical fiber relative to a mount surface. Typically, a sleeve is disposed over the optical fiber adjacent to its end. The clip comprises a clip body having upper and lower surfaces with a flange disposed adjacent to the lower surface. The flange is affixable to the mount surface, and walls extend from the upper surface of the body to define a channel at which the clip is affixable about the sleeve. Advantageously, when the sleeve is affixed within the channel, the body rigidly couples the sleeve to the flange, thereby avoiding misalignment between the optical fiber and any optical device which is on or supported by the mount surface.

摘要： Wavelength division multiplexed couplers are provided with the ends of input and output optical fibers arranged with respect to GRIN lens so that light from one input fiber is directed toward one output fiber with little crosstalk. An integrated wavelength division multiplexed coupler and isolator device useful for connecting fiberoptic amplifiers to pump lasers is also provided with one version of the WDM coupler. The integrated WDM coupler and isolator device has a tap coupler component created by a planar grating which deflects a small portion of the light through the device toward a photodetector circuit for monitoring purposes. The integrated device also may be combined with a laser diode subassembly can be combined to eliminate a pump laser connection for the fiberoptic amplifier.

摘要： An improved optical switch having a first optical fiber and a plurality of N optical fibers. The first optical fiber forms an optical path with any one of the N optical fibers by an alignment of a longitudinal axis of an end of the first optical fiber with a longitudinal axis of an end of the one of N optical fibers. A switch in optical path is performed by a relative movement of the first optical fiber with respect to the N optical fibers for a realignment of the longitudinal axis of the end of the first optical fiber with a longitudinal axis of an end of another one of the N optical fibers.
