Latest Patents
Ulrich D Keil's patent, titled "Al.sub.x Ga.sub.1-x as probe for use in electro-optic sampling," introduces a new electro-optic sampling probe with femtosecond resolution. This advanced probe is significantly thinner and has a dielectric constant that is four times less than the best-reported conventional bulk LiTaO.sub.3 probes. Furthermore, the ultimate bandwidth of this probe is 50 percent greater than that of an equivalent LiTaO.sub.3 probe. The design utilizes a thin film of Al.sub.x Ga.sub.1-x As, which is effective in both total internally reflecting and free-standing geometries. The choice of x is critical for ensuring sufficient transmission of the crystal to the wavelength of the laser source used for electro-optic sampling. The film's thickness is a small fraction of prior art probes, optimized for speed and sensitivity in electro-optic sampling. This innovative thin film probe addresses many issues associated with bulk crystals used as electro-optic sensors.
