Propagating Modes in Subwavelength Cylindrical Holes in an Optically Thick Metallic Film
Stanford Reference:
S04-322
The transmission of light through holes smaller than the wavelength of incident light is significantly increased in a new region of operation that has been identified and analyzed. The analysis shows that light can be transmitted through a high-density packing of nano-dimensional cylindrical holes in optically thick metallic film without diffraction. Based on this analysis, single holes and hole arrays which transport light via the newly-identified propagating modes were designed.
Device and Method for Manufacturing low cost 1.3um VCSEL for Optical Communications
Stanford Reference:
S00-062
This invention enables the low cost fabrication of an optical-electronic semiconductor device for that operates at wavelengths above 1.2 microns, particularly for optical communication systems. This technology overcomes many of the current problems facing optical communications systems. This GaInNAs materials system is very promising for this application as it allows the fabrication of VCSELs at 1.3 um by combining a 1.3 um active region with the already well-developed AlAs/GaAs mirror technology.
Analog and Gray-scale-digital Compression for Video Stored in Volume Holographic Media
Stanford Reference:
5,877,873
This invention increases the storage capacity for video images in holographic media by reducing the crosstalk between adjacent images. The method uses a differential approach, where changes with respect to a base image are recorded rather than the images themselves. The technique eliminates the recording of redundant images, such as background images, and thus reduces the average intensity of the stored pages. Reduced image intensities lead to reduced interpage crosstalk and increased data storage capacities. The differential technique also enables coherent video compression, which eliminates the need for the time-consuming encoding and decoding steps required in electronic compression. Thus, the invention enables a high capacity video image storage system with rapid readout capabilities.
A Diode Laser Pumped and Mode-Locked Solid State Laser in a Three Mirror Cavity Configuration
Stanford Reference:
S87-067
This invention relates to the development of an all solid-state mode-locked laser. The efficiency of the diode pumped solid-state lasers, and the generation of the shortest possible mode-locked pulse width depend a great deal on the overall design of the laser. Another hallmark of a good design is the capability of scaling up to high average output power levels without sacrificing the performance and the efficiency of the laser. The present invention addresses these two issues in a unique manner.
