Comparison of transmission and the 90-degree holographic recording geometry.

چکیده
We compare the system performances of two holographic recording geometries using iron-doped lithium niobate: the 90-degree and transmission geometry. We find that transmission geometry is better because the attainable dynamic range (M/#) is much higher. The only drawback of transmission geometry is the buildup of fanning, particularly during readout. Material solutions that reduce fanning such as doubly-doped photerefractive crystals make transmission geometry the clear winner.

Pixel size limit in holographic memories.
The bandwidth of holographic recording in LiNbO(3) (Fe doped) in the 90 degrees geometry is studied theoretically and experimentally. The wide holographic bandwidth of LiNbO(3) makes it possible to record submicrometer pixels and reconstruct them by phase conjugation in a holographic memory system. This approach reduces the system cost and increases the system storage density. We demonstrate th...
متن کاملHOE for clock distribution in integrated circuits : Experimental results
This paper reports the design and fabrication of transmission holographic optical elements (HOEs) for clock distribution. First, we have studied and fabricated a multi-focus doublet HOE. The aberrations due to the wavelength shift between recording (= 488 nm) and reconstruction ( = 780 nm) have been minimized by an appropriate recording and readout geometry. The diffraction efficiency has been ...
متن کاملVersatile holographic data storage system for angular multiplexing with no upper limit of the angular sweep of the reference beam
We propose and demonstrate a versatile holographic storage system using a single-mode polarizationmaintained PM fiber guided reference beam. By properly allocating the output coupler of the single-mode fiber, the system provides the ability of angular multiplexing recording with no upper limit of the angle tuning range of the reference beam. In addition, this system can easily achieve different...

متن کاملCylindrical Beam Volume Holograms Recorded in Reflection Geometry for Diffuse Source Spectroscopy
Multimodal multiplex spectroscopy (MMS) has been demonstrated to increase the optical throughput of a spectrometer as opposed to that of conventional optical spectrometers [5] and has been implemented using three-dimensional photonic crystals [5] and spherical-beam volume holograms recorded in the transmission geometry [6-7, 9] as spectral diversity filters. While such efforts have resulted in ...
