Paper Abstract

We report the formation of a graded index (GRIN, n equals 1.4 - 1.6) single-mode polymer waveguide lens on a GaAs substrate. The physical dimension of the waveguide lens is defined by the pre-designed mask pattern. The photo lime gel we used is extracted from animal tissue. When dried, this biophotopolymer is a rigid glass film that shows very little absorption or optical scattering. It is soluble in aqueous solutions and insoluble in most organic solvents such as benzene, acetone, petroleum ether, and absolute alcohol. As a result of this, negative photoresist was used as a masking layer for emulsion sensitization. The recording of the chirp grating lens can be realized either by lithographic tool or by holographic recording.
