Title:
PHOTOSENSITIVE RESIN COMPOSITION, METHOD FOR CONTROL OF REFRACTIVE INDEX, AND OPTICAL WAVEGUIDE AND OPTICAL COMPONENT USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/029816
Kind Code:
A1
Abstract:
Disclosed are: a resin composition for the formation of an optical waveguide, which shows low propagation loss and high heat stability and enables to form a waveguide pattern at high shape accuracy and at low cost; an optical waveguide; a method for forming an optical waveguide; and an optical element using the method. A photosensitive resin composition is used, which is characterized by comprising (A) a polyamic acid represented by the general formula (I) or a polyamic acid ester, (B) a compound having an epoxy group, and (C) a compound which can generate an acid upon being exposed to light.
