Abstract

Poly[p-(N-N-dimethylamino)-N-a-D-glutamanilide] has been shown previously to exhibit up to 145% expansion of volume upon exposure to UV light and subsequent development. A thin layer (5 mm) bound to a glass substrate was exposed. Readout of the developed and dried samples by one of the recording beams was accomplished. After exposure at g = 360 nm with 3.2 J/cm2 and at 4.3 mm fringe spacing, we observed 0.4% of the incident power in each first order. Recording at g = 488 nm with 200 J/cm2 also produced diffraction gratings. All indications were that a volume phase hologram was formed.
