Recent Advances in the Photorefraction of Doped Lithium Niobate Crystals
The recent advances in the photorefraction of doped lithium niobate crystals are reviewed. Materials have always been the main obstacle for commercial applications of photorefractive holographic storage. Though iron-doped LiNbO3 is the mainstay of holographic data storage efforts, several shortcomings, especially the low response speed, impede it from becoming a commercial recording medium. Thi...
متن کاملFabrication of high-Q lithium niobate microresonators using femtosecond laser micromachining
We report on fabrication of high-Q lithium niobate (LN) whispering-gallery-mode (WGM) microresonators suspended on silica pedestals by femtosecond laser direct writing followed by focused ion beam (FIB) milling. The micrometer-scale (diameter ~82 μm) LN resonator possesses a Q factor of ~2.5 × 10(5) around 1550 nm wavelength. The combination of femtosecond laser direct writing with FIB enables ...
متن کاملCalligraphic poling of Lithium Niobate.
We demonstrate a novel technique for instituting complex and arbitrary shaped micron-scale domain patterns in LiNbO3 at room temperature. Fabrication of continuous domains as narrow as 2 microm across and hexagonal patterns of the same order accompanied by real time visualization of the poling process are presented.
متن کاملOf Multiple Hologram Recording in Lithium Niobate
The results of detailed experimental and theoretical considerations relating to multiple hologram recording in lithium niobate is reported. The following problem areas are identified and discussed: 1) the angular selectivity of the stored holograms, 2) interference effects due to the crystal surfaces, 3) beam divergence effects, 4) material recording sensitivity, and 5) scattered light from mat...
متن کاملGbit / s Lithium Niobate Modulator
As 10 Gbit/s long-distance optical communication systems become more and more pervasive, requirements rise relating to increased levels of performance, as well as the miniaturization of key devices that configure such systems. Lithium niobate (LN) modulators are used primarily as optical modulators that change high-speed electrical signals at 10 Gbit/s to optical signals for long-distance commu...
