Optischer Koppler zur Ueberkopplung beliebiger Leistungen zwischen Lichtwellenleitern

DE 102005054670 A1 UPAB: 20070806 NOVELTY - Optical coupler has a first wave guide (WG1) which is separated by means of multi mode interference performance fraction (1) in two wave guide part (WG1.1,WG1.2) with equal performance fraction. The both wave guide part are arranged at a certain distance with a defined distance (f) parallel to each other. The second wave guide (WG2) is arranged at a distance (LK) with a distance (g), parallel and symmetrical to both wave guide part. DETAILED DESCRIPTION - The symmetrical over coupling of the two wave guide part takes place on the second wave guide whereby the level of the coupling is adjustable by the length of the distance. USE - For over coupling of arbitrarily adjustable performance fractions from first wave guide into second wave guide. ADVANTAGE - Ensures simple and economical manufacturing, whereby the distance of wave guides permits large tolerances to each other
