摘要： Isolateur optique amélioré, du type comprenant une fibre optique d'entrée (17), une première lentille à gradient d'indice GRIN (11), un premier polariseur (12), un dispositif de rotation optique (13), un second polariseur (14), une seconde lentille GRIN (15), et une fibre optique de sortie (18). Des cristaux biréfringents en niobate de lithium sont utilisés pour réduire le coût et améliorer les performances de l'isolateur. Des améliorations apportées à ce dernier résident également dans le fait que l'extrémité de la fibre optique d'entrée est polie en oblique et est recouverte d'une fenêtre sur laquelle a été appliqué un matériau antireflet. La surface de la lentille GRIN (11) orientée vers l'extrémité de la fibre optique d'entrée (17) est polie en oblique de façon inverse par rapport à l'extrémité, et est séparée de la fibre par un espace qui évite toute interférence de Pérot-Fabry.

摘要： Methods and apparatuses for tuning optical devices are described. Optical devices can be tuned by inserting tuning plates into the optical path(s) of the devices. Tuning plates can be, for example, quartz plates. By selecting the appropriate thickness and optical axis orientation, the tuning plate can be used to tune the optical devices to precision that is unavailable through manufacturing specifications and tolerances of the components of the optical device alone. Because quartz has a relatively small birefringence, tuning plates made with quartz can be thicker, and therefore manufactured more precisely than the components of the optical devices.

摘要： A fiberoptic coupler capable of many functions is presented. The basic fiberoptic coupler has a first sleeve (33), a second sleeve (36), a first collimating GRIN (34) or conventional lens, and a second collimating lens (35) or conventional lens. The first sleeve (33) holds end sections of two or more input optical fibers (30, 31) along the longitudinal axis of the sleeve. The second sleeve (36) holds an end section of at least one output optical fiber (32). The end face of the second sleeve faces the first sleeve end face. The first collimating GRIN (34) or conventional lens in front of the first sleeve end face collimates light signals from the input optical fibers and the second collimating GRIN (35) or conventional lens in form of the second sleeve end face focusses light signals from at least one of the input optical fibers (30, 31) into the single output fiber (32), or at least one of the output optical fibers (32, 39). 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 can be inserted between the first and second collimating lenses.

摘要： An optical device which controls the strength of an optical signal from an input fiber (27) to an output fiber (28) responsive to a signal on a control terminal. The device has a first GRIN lens (21) associated with the input fiber (27), a first birefringent polarizer (22), a liquid crystal cell (20), a second birefringent polarizer (24) and a second GRIN lens (25) associated with the output fiber (28). The liquid crystal cell (20), located between the first (22) and second (24) polarizes and connected to a control terminal, controllably rotates the optical signal from the optical axis of the first polarizer toward the optical axis of the second polarizer responsive to the signal on said control terminal. The operation of the device is independent of the polarization of the optical signal in the input fiber. Furthermore, the device can be operated as an optical switch or an optical attenuator by suitably arranging the axes of the polarizers and liquid crystal cell.

摘要： The present invention relates to interleaver/deinterleaver devices for combining/separating optical channels. An interleaver/deinterleaver is "folded" when an optical signal follows an optical path that passes through a birefringent assembly multiple times. Double-pass refers to optical signals following a (folded) path through the birefringent assembly twice. Multi-pass refers to optical signals following a (folded) path through the birefringent assembly multiple times. When operating as a deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g., WDM signal) into subsets of optical signals (e.g., even and odd ITU channels). When operating as an interleaver, the interleaver/deinterleaver mixes subsets of optical signals into a multiplexed optical signal. The interleaver/de-interleaver can be used to increase the bandwidth of an optical network. For example, the interleaver/deinterleaver can be used to interface components designed for a first channel spacing (e.g., 100 GHz) to components designed for a second channel spacing (e.g., 200 GHz). Folded interleaver/deinterleavers cause dispersion because the speed at which the ordinary beam of an optical signal passes through the birefringent assembly is different that the speed at which the extraordinary beam of the optical signal passes through the birefringent assembly. In order to reduce or eliminate dispersion, the polarization of the optical signal is reversed for alternating passes through the birefringent crystal. For example, if a signal is horizontally polarized for a first pass through the birefringent crystal, the signal is rotated so that it is vertically polarized for a second pass through the birefringent crystal. For a third pass through the birefringent assembly, the signal is rotated so that it is again horizontally polarized.

摘要： Optical filters, filter systems, and methods for filtering optical signals transmitted along optical fibers (12, 14) provide enhanced filter performing by combining the capabilities of different types of filters particularly for dense wavelength division multiplexed systems. More specifically, the spectral skirt or transition wavelength range between a pass band wavelength range and a blocked wavelength range of a thin film pass band or dichroic filter (16) is enhanced by arranging the thin film filter (16) in series with one or more Fiber Bragg Gratings (18, 20). The Fiber Bragg Gratings (18, 20) will generally reflect a portion of the signal within the spectral skirt or transition wavelength range of the thin film filter (16). Although short Fiber Bragg Gratings generally block a quite narrow range of signals, the steep spectral skirt of the grating, when combined with the broader wavelength response of a thin film bandpass or dichroic filter (16), results in a composite filter structure which exhibits the beneficial characteristics of each of its components.
