Abstract: The present invention discloses methods and apparatus for constructing optical switch systems, in which any input optical signals can be routed to any output ports. The methods and apparatus provide advantages of configuration flexibility, modular construction, constant signal loss, and minimal numbers of switch units required. The switch systems comprise MxN switch modules (10). The switch module (10) in turn comprises a two−dimensional waveguide array and a number of waveguide grating−based wavelength selective switches (130). With the capability of wavelength−selective routing provided by the switch modules, the optical switch systems requires a relatively small amount of switch units to extend into a very− large− scale switch system.

Abstract: A diffraction grating device according to the present invention is a diffraction grating device in which a diffraction grating based on perturbation of refractive index is formed through a predetermined range in a light guide direction in an optical waveguide and in which the diffraction grating selectively reflects light in a reflection band out of light guided through the optical waveguide. In the diffraction grating device, the reflection band is divided into K (K ≥ 2) wavelength bands, and the perturbation of refractive index Δn all in the predetermined range is represented by the sum of index perturbations Δn k (k = 1-K) of periods Λ k according to the respective K wavelength bands. Furthermore, at least one set of phases out of phases ϕ k (k = 1-K) of the index perturbations Δn k at a center position of the predetermined range are different from each other. This permits provision of the diffraction grating device in a short total length, at low cost, and with excellent reflection and transmission characteristics.

Abstract: The present invention is a fused/taper fiber optic coupler and related methodologies for a fuse/taper fiber optic coupler with an FBG (508) that does not excite cladding modes and maintains the coupling regions of the fibers (100, 503, 504) in the proper relationship to one another without a complex and expensive process. As will be explained in greater detail below disclosed aspects of the fused/taper fiber optic coupler include the use of optical fibers (100, 503, 504) with a three layer structure. The optical fibers include a photosensitive core layer (106), a photosensitive inner cladding layer (104), and a photo-insensitive outer cladding layer (102). Coupling regions (506, 202) are formed in each optical fiber (100, 503, 504) by removing the outer cladding layer (102) and the coupling regions in each optical fiber (100, 503, 504) are then helically intertwined. The intertwined coupling regions are then heated and drawn forming a tapered area in which an FBG may be written.

Abstract: A wavelength selective optical fiber coupler having various applications in the field of optical communications is disclosed. The coupler is composed of dissimilar waveguides (12, 22) in close proximity. A light induced, permanent index of refraction grating (42) is recorded in the coupler waist (52). The grating filters and transfers energy within a particular range of wavelengths from a first waveguide (12) to a second waveguide (22). Transversely asymmetric gratings provide an efficient means of energy transfer. The coupler can be used to combine or multiplex a plurality of lasers operating at slightly different wavelengths into a single fiber. Other embodiments such as a dispersion compensator and gain flattening filter are disclosed.

Abstract: Appareil (Fig. 2) du type comprenant un ensemble optique (9), par exemple une lentille (11) et une grille de réflexion (13), pour effectuer la collimation de la lumière émise par un laser (L1'), et pour la focaliser sur une guide d'onde (7) de sortie. Le guide d'onde (7) est modifié pour augmenter la réflexion de la lumière refocalisée, qui à son tour domine la réponse résonante du laser (L1'). La résonance du laser dépend ainsi de facteurs géométriques, les positions relatives du laser (L1') et du guide d'onde (7) ainsi que les propriétés de dispersion de l'ensemble (9). On peut améliorer la sélectivité en fonction de la longueur d'onde en limitant la réflexion au noyau du guide d'onde (7), par exemple en utilisant un réflecteur intégré, ou encore une paire d'étalons (17, 17'). Le laser (L1') peut être utilisé conjointement avec d'autres lasers (Ln') et/ou des détecteurs, ou bien avec des rétroréflecteurs (27). Un multiplexeur (Fig. 2) d'entrée multilaser et des dispositifs d'élimination et d'addition (Fig. 7; Fig. 10) à un seul canal sont décrits.
