Fabrication Applications of GRIN Materials
In recent years, a series of gradient index (GRIN) materials including Optical glass and polymer have been Research and developed in our laboratory. The Micro-lenses and arrays with the special optical materials also have been fabricated mainly by using Ion-exchange method through refractive index profile, which are applied to micro-optic devices and other applications—— especially in the coupled and connected devices for fiber communications and medical endoscope or they are used primarily for document scanning equipments.
