Abstract: PROBLEM TO BE SOLVED: To form substantially flat plane type optical circuits by treating a glass body to overcome troubles, such as distortion curling. SOLUTION: A substantially flat plane type silica substrate is formed and plural layers of oxide compds. are formed on this substrate. These oxide layers are sintered to form glassy optical waveguide layers on the silica substrate. The structural body formed in such a manner is heated to a high temp. for the time sufficient for flattening the structural body and the optical circuits are formed in the glassy layer by the conventional photolithography and etching. The surface formed in such a manner is clad with a glass layer covering the surface having the refractive index substantially equal to the refractive index of the substrate.

Abstract: Un método para formar un circuito optico de onda luminosa plano, substancialmente liso, que tiene un substrato de sílice plano substancialmente liso y una capa de guía de onda cristalina concrecionada sobre el substrato de sílice; se da un tratamiento posterior a la estructura a una temperatura elevada durante un tiempo suficiente para alisar dicha estructura y compensar distorsion; alternativamente, el substrato de sílice puede calentarse y combarse previamente hasta un grado predeterminado para compensar la distorsion o combadura que ocurre en tratamiento posterior.

Abstract: A new multiplexer/demultiplexer (50) includes a compound focusing mechanism having adjacent focal points (F1,F2). 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 vacinity 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: The demultiplexer comprises: a) an inlet wave-guide (1); b) a plurality of outlet wave-guides (5i); c) an assembly (3) of adjacent integrated wave-guides functioning in the form of a phase network; d) a mode-expanding wave-guide (12) arranged at the inlet of the inlet connector (2) and connected to the inlet wave-guides (1); and e) a plurality of mode-reducing wave-guides (16i) arranged at the outlet of the outlet connector (4) and connected in each case to one of the outlet wave-guides (5i). The mode-expanding guide (12) and the aforementioned mode-reducing guides (16i) are of identical geometry with a width that varies linearly in accordance with their length, whereby the width of the aforementioned expanding and reducing guides at their connection to the associated connector is defined in order to optimize the width of the band passing through a channel while limiting the cross-talk between the outlet channels (5i) to a pre-determined level.

Abstract: A method for forming a substantially flat planar lightwave optical circuit which has a substantially flat planar silica substrate and a sintered glassy lightguiding layer over the silica substrate. The structure is given a post treatment at an elevated temperature for a time sufficient to flatten said structure and compensate for distortion. Alternatively, the silica substrate may be heated and presagged to a predetermined degree to compensate for distortion or warpage which will occur in later processing.

Abstract: The invention comprises (a) a divider (D) by 2 of the optical power received at one input (E1, E2) and (b) two groups of single mode waveguides coplanar to the divider and symmetrical relative to the axis of symmetry (Z) of the divider (D), each group being composed of waveguide sections connected in tree and branch fashion by Y junctions (J11) between one input junction (J11, J12) connected to one of the outputs of the divider and N sections of waveguide difining N outputs (S1 to S16) of the coupler parallel to the axis of the divider. According to the invention, each of these input junctions (J11, J12) has a rectilinear input branch (B1) with predetermined length such that the transverse distribution of the optical power at the output of the rectilinear input branch (B1) is centered to a large degree on the axis of this input branch.
