Optisches Bauelement und Verfahren zum Schalten oder Modulieren von Licht

WO 9953365 A UPAB: 20000105 NOVELTY - The optical component has a waveguide (8) formed between input and output regions. The waveguide is adjacent to a diffraction area (3). Either the diffraction area or the waveguide consists of a material with a variable refraction index. The waveguide has at least one totally reflecting delimiting section (4) and a device for varying the refraction index arranged perpendicularly to the delimiting section. USE - Controlled light transmission. ADVANTAGE - Improved performance
