Abstract: PROBLEM TO BE SOLVED: To obtain a new multiplexer demultiplexer including a compound focusing mechanism which has adjacent focuses. SOLUTION: Many images of >=1 input paths are projected on >=1 output path as to individual signals which differ in wavelength. The obtained spectrum response is flattened nearby the center wavelength of each different-wavelength signal. The number and interval of the focuses and the mode field radii of the input and output paths can be optimized as to a desired combination of channel bandwidth, insertion loss, and crosstalk.

Abstract: Un nuevo multiplexor/desmultiplexor incluye un mecanismo de enfoque compuesto que tiene puntos focales adyacentes; imágenes multiples de una o más trayectoria de entrada para cada señal de longitud de onda diferente son proyectadas sobre una o más trayectorias de salida; la respuesta espectral resultante es aplanada en las inmediaciones de la longitud de onda del centro de cada señal de longitud de onda diferente; el numero y separacion de los puntos focales, así como los radios del campo de modo de las trayectorias de entrada y salida se pueden optimizar para combinaciones deseadas de ancho de banda de canal, pérdida de insercion y diafonía.

Abstract: A new multiplexer/demultiplexer includes a compound focusing mechanism having adjacent focal points. Multiple images of one or more input pathways for each different wavelength signal are projected onto one or more output pathways. The resulting spectral response is flattened in the vicinity of the center wavelength of each different wavelength signal. The number and spacing of the focal points, as well as the mode field radii of the input and output pathways, can be optimized for desired combinations of channel bandwidth, insertion loss, and crosstalk.

Abstract: A tradeoff between crosstalk and channel bandwidth in dense wavelength demultiplexers is achieved by varying mode fields of input and output waveguides. Funnels are formed between inner and outer ends of the input and output waveguides to increase mode field radii, which results in decreased crosstalk attenuation but larger bandwidth channels.

Abstract: A flat planar light wave optical circuit is formed by a method(A) comprising: (i) forming a layer of a plurality of oxide compounds on the surface of a flat planar silica substrate, (ii) sintering the oxide layer to form a glassy light guide layer, (iii) heating the structure at an elevated temperature for a time sufficient to flatten the structure, (iv) forming an optical circuit into the glassy layer by photolithography and etching, and (v) cladding the surface with a glassy layer having the same index of refraction as the substrate.

Abstract: The device consists of a dual-mode waveguide 1 that has a longitudinal axis ÄXÜ, a length ÄLÜ, and a width ÄWÜ, and two pairs of monomode waveguides 2,3 and 4,5, for entry and exit, respectively. In accordance with the invention, the length ÄLÜ and the width ÄWÜ of the dual-mode waveguide Ä1Ü are selected in such a way as to establish, in this guide, light coupling that is greater in the window from 1260 to 1360 nm than in the window from 1480 to 1580 nm, so as to compensate for the significant contrary proximity coupling in these windows, as created between the monomode entry guides 2 and 3 on the one hand and the monomode exit guides 4 and 5 on the other hand. Application to the creation of a 2 x n coupler that has low insertion losses and that is achromatic within the spectral windows from 1260 to 1360 nm and from 1480 to 1580 nm.
