The Composite Structure of Hologram and Optical Waveguide

Optical holography is an excellent technology which can be applied in many fields, such as 3D-displays, information storage, products packaging, interferometer survey, optical connection and computer and so on. The conventional holography include reference wave, object wave and diffracting wave. These optical waves are spatial light and the whole hologram set up is fair size. The optical waveguides which are set up in optical routs can be integrated into a mini-chip. A new class of holography is proposed by many researchers [Suhara, et al., 1976; Putilin, et al., 1991; Singher & Shamir, 1994], in which the evanescent part of a guided wave or the guided wave in a waveguide is utilized as the reference wave or the illuminating one. This kind of hologram is defined as “waveguide hologram”, and it has significant advantages in integration, wide field of view, compactness and other special functions. In this chapter, three sections are used to introduce the new development of waveguide hologram in the optical memory, optical connection and see-through planar displays fields.
