Abstract
The underlying physical phenomena behind the increased reflection/diffracti on efficiency of holographically formed polymer-dispersed liquid crystal gr atings formed from blended oligomers are investigated. Using parameters det ermined by in situ diffraction measurements during grating formation, a phe nomenological diffusion model shows that a composition modulation in the po lymer network results in blended oligomer systems. Scanning electron micros cope studies reveal polymer morphologies consistent with this hypothesis. ( C) 2000 American Institute of Physics. [S0003-6951(00)05216-5].
