Abstract: Un dispositivo de fibra optica para su uso en un sistema de transmision de fibra optica y componentes de los mismos incluye una fibra de paso continuo y una o más longitudes de fibras circulantes conectadas a la fibra de paso continuo por los respectivos conmutadores opticos para enviar selectivamente una señaloptica a través de las longitudes circulantes de fibra conforme se propaga a lo largo de la fibra de paso continuo. Las longitudes de fibra circulante son o bien fibras compensadoras de dispersion o fibras impurificadas con una substancia que amplifica o absorbe la señal optica en la respectiva presencia o ausencia de una señal de bombeo. La invencion permite por lo tanto que se conecten selectivamente varias cantidades de dispersion o ganancia (absorcion) para su uso o desuso dependiendo de las necesidades al momento. Por ejemplo, un componente amplificador que podría servir como un dispositivo amplificador previo o de potencia o en línea dependiendo de la menor o mayor cantidad de fibra de ganancia elegida por medio de conectar; se puede interconectar el dispositivo con el sistema de transmision o los componentes del mismo por medio de empalmar a los extremos de la fibra de paso continuo o por medio de los conmutadores opticos conectados a los extremos de la fibra de paso continuo.

Abstract: An optical amplifier includes an optical feedback resonant laser cavity (OFR C) including a power dependent loss element (PDLE) having the characteristic th at as the incident laser power on the PDLE increases the cavity loss decreases. The OFRC with the PDLE provides optical gain control or optical power contro l for a WDM amplifier or a single channel power equalization amplifier (PEA), respectively. A 1xNxN WADM node incorporating more than one of these amplifiers, at least some of which commonly share a pump source, and a metho d for controlling a transient power change in a single channel optical amplifi er or reducing a DC gain error in a WDM optical amplifier that are subject to dynamically variable operating conditions at an input of the amplifier, are also disclosed.

Abstract: A package for a high power semiconductor laser comprising a hermetically sealed container filled with a dry gaseous medium containing oxygen. The package also may include a getter for organic impurities, e.g., a getter composed of a porous silica or a zeolite. The hydrogen content of the materials used to form the package can be reduced by baking at an elevated temperature for an extended period of time, e.g., at 150 DEG C for 200 hours.

Abstract: Disclosed is a family of dispersion compensating optical fibers that are adapted for use with conventional single-mode transmission fibers that are optimized for zero dispersion operation at a wavelength in the range from 1290 nm to 1330 nm to form a transmission link suitable for low dispersion operation in the 1520-1565 nm wavelength window. The dispersion compensating fibers are capable of providing a dispersion more negative than -20 ps/nm-km and attenuation less than 1 dB/km at wavelengths in the 1520-1565 nm region. Certain of the dispersion compensating fibers also exhibit a dispersion versus wavelength relationship having a negative slope in the 1520-1565 nm region, to compensate for the dispersion versus wavelength slope of the trandsmission fiber. The dispersion compensating fiber can be advantageously combined with a fiber amplifier to form a compensator that is adapted to overcome attenuation introduced into the system by the dispersion compensating fiber. In one embodiment, the dispersion compensating fiber is also a distributed fiber amplifier.

Abstract: Disclosed is a fiber amplifier system including a gain fiber having a single-mode core doped with active dopant ions capable of producing stimulated emission of light at wavelength .lambda.s when pumped with light of wavelength .lambda.p. Spliced to the gain fiber is a light-attenuating fiber having a core containing a dopant that attenuates light of wavelength .lambda.p but not .lambda.s. The amplifier is conventionally employed in a system including an incoming telecommunication fiber for introducing light of wavelength .lambda.s into an end of the gain fiber, the amplified signal being connected to an outgoing telecommunication fiber. The system further includes a pump source for introducing light of wavelength .lambda.p into an end of the gain fiber. Elements of the system can be arranged for forward pumping, counter pumping and dual ended pumping. Various interconnection schemes are disclosed for forming a series arrangement including the gain fiber, the attenuating fiber and the outgoing fiber.

Abstract: An optical signal amplifier with a waveguide path integrated into a glass body that is doped with optically active material. The signal to be amplified is transmitted through the waveguide and the pump power is coupled into the waveguide at one end. The waveguide comprises closely spaced adjacent guide lengths in the form of a spiral, zigzag paths between mirrors, or parallel paths with connecting semicircles at alternating ends of succeeding pairs of paths.

Abstract: A fiber optic device for use in fiber optic transmission systems and components thereof includes a pass-through fiber and one or more lengths of circulating fiber connected to the pass-through fiber by respective optical switches for selectively routing an optical signal through the circulating fiber lengths as it propagates along the pass-through fiber. The circulating fiber lengths are either dispersion compensating fibers or fibers doped with a substance that will amplify or absorb the optical signal in the respective presence or absence of a pump signal. The invention thus allows various amounts of dispersion or gain (absorption) to be selectively switched into or out of use depending upon requirements at the time. For example, an amplifying component could serve as a pre- or power- or in-line amplifier device depending on the lesser or greater amount of gain fiber elected by switching. The device can be interconnected with the transmission system or components thereof via splicing to of the ends of the pass-through fiber or via optical switches connected to the ends of the pass through fiber.
