PCT No. PCT/EP96/00493 Sec. 371 Date Oct. 4, 1996 Sec. 102(e) Date Oct. 4, 1996 PCT Filed Feb. 6, 1996 PCT Pub. No. WO96/24869 PCT Pub. Date Aug. 15, 1996The 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.
