Preferential doping of rhodamine 6G in a polyurethane optical solid circuit

Abstract

Introduction of a dye doped region into a passive waveguide area has been established by thermal doping of organic dye in a polymer optical solid‐state circuit. Using periodical corrugations with a period of 2050 Å formed on a glass substrate, a N₂ laser pumped dye laser—waveguide system has been constructed.
