摘要： The present invention concerns a method for constructing a light coupling system wherein a grating is manufactured on the surface of a multimode waveguide and defines the entrance of the waveguide for an incident light beam, said grating comprising a repetition of patterns. The grating is defined by a set of parameters comprising: •grating period (P), separating two adjacent patterns, •grating depth (d) between the highest and the lowest point of the pattern, •incident angle mean value (θ) of the incident light with respect to the waveguide. The method comprises a step of optimization of the set of parameters to obtain an optimized second set of parameters, in order to obtain a transmission efficiency (Ce) of the incident light into said waveguide for the first or the second diffractive order exceeding 35% for unpolarized light, or exceeding 50% for polarized light, at a given wavelength of the incident light.

摘要： An optical multiplexing device includes an optical element having at least one set of diffractive elements, and an optical reflector. The reflector routes, between first and second optical ports, that portion of an optical signal transmitted by the diffractive element set. The diffractive element set routes, between first and multiplexing optical ports, a portion of the optical signal that is diffracted by the diffractive element set. More complex optical multiplexing functionality(ies) may be achieved using additional sets of diffractive elements, in a common optical element (and possibly overlaid) or in separate optical elements with multiple reflectors. Separate multiplexing devices may be assembled with coupled ports for forming more complex devices. The respective portions of an optical signal transmitted by and reflected/diffracted from the diffractive element set typically differ spectrally. The portion reflected from the diffractive element set may comprise one or more channels of an optical WDM system.

摘要： A wavelength division multiplexed optical communication system comprises an optical waveguide having a plurality of gratings, each defining a node. A first grating is disposed at a first node couples impinging light at a plurality of preselected wavelengths into the waveguide. The coupled light propagates through the waveguide and is emitted at a second and at a third grating in directions corresponding to each of the preselected wavelengths. A plurality of optical sources is arranged proximate the first node, each source transmitting an optical signal at a preselected wavelength that differs from that transmitted by the other sources and arranged to transmit light to the first grating. Optical detectors are disposed proximate the second and the third nodes, and positioned in directions corresponding to the emitted light. Thus each detector detects one of the preselected wavelengths. This constitutes a broadcast type of communication system.
