We have developed aromatic polyester (polyarylate) for the optical devices. New polyarylate (PAR-A, PAR-B) are excellent for transparency in the visible spectrum, and thermal stability. We found that the birefringence of PAR-A is very low. PAR films are produced easily by spin-coating or solution-casting, and can be patterned by RIE method. We fabricated ridge waveguides patterned in new polyarylate.
