摘要： Optical waveguide devices based on optical coupling of different modes by using a mediating mode. Such waveguide devices generally have at least two coupling regions. The first coupling region couples an output mode and the mediating mode, and the second one couples the mediating mode and an input mode that copropagates with the output mode. Under proper conditions, the energy in the input mode can be completely transferred to the output mode, without energy loss to the mediating mode.

摘要： The present invention provides fiber optic couplers for use with at least three optic fibers. The optic fibers arranged in a linear array, that is, the optic fibers are coupled side by side. The fibers along either end of the linear-array are coupled only to a single fiber, while the remaining fibers are generally coupled between only two adjacent fibers. Generally, at least one of the fibers has a propagation constant different that the other fibers. Such variations in the propagation constant are used to vary the coupling coefficients among the fibers of the linear-array, thereby providing a repeatable mechanism, to vary coupled power ratios among the fibers of the coupler. Theoretical calculations and empirical experience have shown that varying the propagation constant of fibers among a linear-array, generally by pre-pulling the fibers by varying amounts, allows repeatable manufacturing of 1.times.3, 1.times.4, 4.thrfore.3, 1.times.N and even N.times.N fiber couplers having even coupled power ratios.

摘要： The present invention relates to an optical coupler 2.times.2 optical switch which can efficiently shorten the length of device by employing a cantilever and a movable optical waveguide and a method for optical switching with the optical coupler 2.times.2 optical switch. An optical coupler 2.times.2 optical switch of the present invention comprises: an optical coupler in which two fixed optical waveguides are provided on a substrate; an optical waveguide positioned between the fixed optical waveguides, which is moved up and down; and, a cantilever which is linked to the optical waveguide to move the optical waveguide up and down by the voltage applied to electrodes. Since the coupling length of the optical coupler(22) is changed depending on the distance between the fixed optical waveguides(21, 21') and the optical waveguide(23), length(D) of the optical, coupler(22) can be shortened to a great extent compared to the prior art optical coupler 2.times.2 optical switch, and the insertion loss of the device in the construction of optical communication system can be lowered significantly and optical switching can be carried out with a good performance.

摘要： The invention concerns an integrated-optical junction splitter, in particular for applications in the wavelength range of visible light, which ensures a spatial and wideband combination of light in a wavelength spectrum .DELTA..lambda. greater than 75 nm (value given applies to short-wave visible light). In the case of a usable wavelength range comprising the entire spectrum of visible light, the junction splitter is a white light junction splitter. The junction splitter consists of at least three channel waveguides, at least one of which must be a single-mode integrated-optical wideband channel waveguide (SOWCW). Two channel waveguides each have a respective input and are combined into a common SOWCW at their outputs in a coupling point, which common SOWCW features a common light output at its end. This wideband junction splitter is used as a wavelength-selective or wavelength-independent switch or modulator, in interferometric and photometric devices, sensors, and microsystem-technical solutions.
