Abstract

A new refractive index imaging media system is described, based on the photoinitiated isomerization of dewarbenzene derivatives in a solid polymer medium. The system can exhibit a refractive index contrast as high as 0.02, with low dimensional changes on recording. Furthermore, the medium is highly sensitive because the recording process is chemically amplified, that is, many product molecules are formed per photon absorbed. The change in refractive index occurs spontaneously under blue or UV irradiation; no subsequent processing is required. This system may find applications in holographic recording and for integrated optical devices. For example, many spatially overlapping holographic diffraction gratings were recorded (angular multiplexing) in the material in the same volume.
