Title:
WAVEPLATE AND OPTICAL CIRCUIT FORMED FROM MESOGEN-CONTAINING POLYMER
Document Type and Number:
WIPO Patent Application WO2003034102
Kind Code:
A3
Abstract:
Waveplates formed of mesogen-containing polymers and planar lightwave circuits containing such waveplates. Polymers have sidechains containing mesogens such as biphenyl-containing groups. Polymers may have a glass transition temperature between 100 DEG C and 300 DEG C, and polymers may be stretched in excess of 150% to increase birefringence of polymer and provide thin films. Waveplates formed of stretched polymer films may have high biaxial birefringence.
