“…An alternative approach to achieve polarization selectivity is based on multiple periods of phase delays using a single birefringent substrate (also called modular 2mit), as first proposed in [8] and later in [10]. Such an approach may reduce the cost and simplify the fabrication process of polarization selective diffractive optical elements.…”

Novel diffractive optical elements (DOE) with multifunctionality in polarization or color are reviewed. We review three technological approaches for construction of such DOEs with multifunctionality in polarization: the two-substrate birefringent computer generated hologram (BCGH), the multiple order delay BCGH, and the form birefringent computer generated hologram (FBCGH) approaches. We also discuss the accurate design of such DOEs enabled by our modeling tools based on rigorous coupled wave analysis.Microfabrication techniques developed for realization of these three types of polarization selective DOEs are described. The developed DOEs with multifunctionality in polarization or color are used to package a 3-D optoelectronic VLSI chip, a transparent optical multistage interconnection network, and a wavelength division demultiplexer, providing mechanical and thermal stability, light efficiency, reduced volume, weight, and cost, and increased reliability.

“…The resulting binary and multilevel surface relief gratings are a well-known family of DOEs [1][2][3][4][5][6][7][8]. The spatial phase distributions in the multilevel DOEs are designed by a computer, and the multilevel DOEs are widely applied for the highly functionalized optical devices.…”

“…It is believed that if anisotropic rather than isotropic materials for multilevel DOEs are used, then polarization controllable and/or convertible DOEs can be developed. The multilevel DOEs using anisotropic materials have scarcely been studied, but Liu and Chen presented multilevel binary phase grating polarization device with a birefringent substrate and indicated that a polarizing beam splitter was developed by fabricating the periodic structure of an echelon profile upon the surface of the birefringent substrate [5]. Fratz et al presented and demonstrated the digital polarization holography by using the photoinduced reorientation in the azobenzene-containing polymers.…”

Multilevel anisotropic diffractive optical elements (DOEs), in which digitized spatial patterns of optical birefringence are fabricated by means of stepping photoalignment technique, has been demonstrated using photo-cross-linkable polymer liquid crystals (PCLCs). The polarization state of incident light is converted into a different polarization state by diffracting light in the practical, i.e., transparent in visible region and thermally stable, multilevel anisotropic DOEs, and both polarization azimuth and ellipticity can be widely controlled by their birefringence patterns. Theoretical considerations for such polarization conversion were also performed using the Jones calculus and diffraction theory and well-explained experimental observations.

“…Most PBSs employ the natural birefringent effect 1 ͑for example, Nicol prisms, Wollaston prisms, etc.͒, the diffraction effect 2,3 ͑grating structures͒, the absorption effect 1 ͑dichroic polarizer͒, the refraction effect 4 ͑multilayer structure, e.g., PBS cubes͒, or a combination of two or several of these effects. S. Liu et al proposed a new type of polarization device, 5,6 which combines the birefringent effect with the diffraction effect. This type of PBS is made of a sheet of birefringent material with a periodic structure of an echelon profile or a sawtooth profile on its surface.…”

A new kind of polarizing beamsplitters (PBSs) based on the effects of a birefringent and resonance anomaly is presented. Its properties are analyzed using the correct Fourier modal method and the reflective and transmissive coefficient matrix (RTCM) recursion method. Two examples, one for the IR and the other for the visible, are given. An extremely high polarization extinction ratio is obtained in transmitting space. The effects of small variations in the parameters of the PBSs performance are also investigated. © 2002 Society of Photo-Optical Instrumentation Engineers.
