Abstract (en)
[origin: WO9624869A1] An integrated optical combination splitting device, in particular for applications in the wavelength range of visible light, which ensures a spatial, broadband concentration of light in a wavelength range DELTA lambda greater than approximately 75 nm (valid for short-wave visible light). For a useful wavelength range comprising all visible light, a white-light splitting device is provided. The combination splitting device consists of at least three strip waveguides, at least one of which being a single-mode integrated optical broadband strip waveguide (EOBSW). Two strip waveguides (2, 3) each have an entry point (E1, E2) and are joined at their exit points (A1, A2) in a coupling point (6) to become a joint EOBSW (5) having a common light exit (AM) at its end. This broadband combination splitting device can be used as a wavelength-selective or wavelength-independent switch or modulator in interferometric and photometric arrangements, sensors and microsystem solutions.
