Optical characteristics of photopolymer for holographic applications as a input beam coupler

In this paper, a holographic grating coupler based on the photopolymer has been designed and experimentally demonstrated with photopolymer of HRF 150 series at wavelength of 405 nm and we researched optical properties of OmniDex 700 series for holographic application at 532 nm. To achieve the high diffraction efficiencies in the structure, we investigated the optical properties of the material to the exposure energy and incident angles at the 532 nm wavelength, we researched the optical characteristics of the Dupont photopolymer OmniDex 700(series) and HRF 150(series) for holographic application as a input beam coupler. The performance and the optical characteristics of the volume holographic grating will be discussed in detail.
