摘要： An optical interference filter ( 2 ) is provided by a substrate ( 1 ) in which is formed a plurality of parallel slots so as to define layers (slots and substrate laminae) of alternating refractive index. As shown, the filter comprises a central Fabry-Perot resonator slot cavity ( 3 ) between two mirror groups ( 4, 5 ) of alternating slots and substrate laminae, and is coupled to optical fibers ( 7 ) accommodated in V-grooves ( 6 ) on either side. For tuning, one mirror group ( 5 ) may be movable in the direction of arrow (A), or, where the central resonator is provided by substrate material, by altering its temperature. One or more further Fabry-Perot filters may be formed in the substrate and coupled to the filter ( 2 ). The invention encompasses non-resonating filters.

摘要： Microarrays are imaged by an illumination and detection system that supplies excitation light through one or more optical fibers, each fiber transmitting excitation light from an excitation light source to a single spot in the microarray. Emission light from each spot is then collected by a collimating lens and converted to a signal that is compiled by conventional software into an image of the entire microarray. The optical fiber(s) and the collimating lens are arranged such that the direction of travel of the excitation light and the direction along which the emission light is collected are not coaxial, and preferably both are at an acute angle to the axis normal to the plane of the microarray.

摘要： An optical fiber array block includes at least one optical waveguide having an optical fiber zone, and an optical device. An optical signal leakage window is formed at the optical waveguide, and the optical device corresponds to the optical signal leakage window. If the optical signal leakage window is formed at an optical fiber comprising a core and a clad layer, the clad layer is partially removed or is partially connected to the core by means of tan ion implantation technique. Thus, the clad layer has a refractive index that is similar to that of the core.

摘要： The invention concerns monomode or multimode optical fibers provided with a lens with an end taper, obtained by selective photopolymerization of a formulation, and with improved performances through the use of novel parameters and technical processes enabling production of polymer tapers with optimized characteristic required for a wide range of applications. The monomode or multimode optical fibers can, for certain specific applications, be equipped with a metallized polymer taper except for a nanometric opening for sensing or emitting light or a polymer taper whereof the formulation contains fluorescent particles. The novel fibers are essential components in various fields such as telecommunications (high performance connectors) or instrumentation (optical radiation comparator probes for scanning optical microscopy and near-field optical microscopy).

摘要： An improved low-loss waveguide crossover uses an out-of-plane, such as vertical, waveguide to bridge over any number of waveguides with very low, or essentially no, optical loss or crosstalk. Optical signals transmitted in a waveguide system having the improved waveguide crossover can cross over one or multiple transverse waveguides with a greatly reduced loss of signal intensity by using a second waveguide (such as a bridge) positioned in a second plane different from the plane containing the transverse waveguides. An optical signal from the input waveguide is coupled efficiently through directional coupling to the bridge waveguide and optionally from the bridge waveguide to the output waveguide. Methods for fabricating the improved waveguide crossover are described.

摘要： An external gain system includes a gain source, a laser coupler, one or more mode converters, a high index contrast waveguide, and a filter structure fabricated on either high or low index contrast waveguides. The filter structure defines the external cavity with the front facet of the laser diode. An external cavity laser is further integrated with one or more functional blocks to perform a specific function. A multiplexer is integrated with the external cavity laser array, where the waveguide ends of the external cavity serve as an input to the multiplexer, to form an integrated WDM transmitter. The output of the transmitter, if fabricated on high index contrast waveguide, is then coupled to a low index waveguide or fiber matched waveguide by using a mode converter. The gain system can be configured to become a linear optical amplifier and can also be configured as a low cost wavelength converter.

The optical filtering device comprises an optical input receiving the optical signal; an elongated waveguide connected to the input and having a modified transverse dimension to create a series of partially reflective segments having predetermined effective indices of refraction (neff) with a distribution within the waveguide to provide the filtering of the optical signal, wherein the segments are designed for single mode operation and wherein a reflected filtered output optical signal is generated, wherein the transverse dimension varies within a narrow range over which a transverse size of the mode remains close to its minimum value; an optical output connected to the waveguide for providing the filtered optical signal.
