Paper Abstract

The potential utilization of volume diffractive elements (VDOEs) in a variety of sophisticated imaging applications has been established. VDOEs are capable of designed-in arbitrary phase distributions (indigenous to multi-layer diffractive structures), while maintaining high diffraction efficiencies (exhibited in volume holographic optical elements (HOEs)). Furthermore, multi-layer VDOE structure facilitates further improvement over HOEs. High diffraction efficiencies with simultaneous side lobe suppression can be achieved in VDOEs, while narrow bandwidths and desirable free spectral ranges are maintained. In this paper, we show that with proper utilization of VDOE and spacer thickness, we can achieve efficient side lobe suppression in the behavior of the diffraction efficiency, as a function of both incident wavelength and angle.
