Appl. No.:

09/634455

Inventors:

Mark A. Itzler - Princeton NJ
Chen Show Wang - Warren NJ
Nicholos J. Codd - Ewing NJ
Suzanne McCoy - Hamilton NJ

Assignee:

JDS Uniphase, Corp. - West Trenton NJ

International Classification:

H01L 310304

US Classification:

257186

Abstract:

A method for designing an avalanche photodiode for high bit rate or high speed applications is disclosed. The photodiode is made up of a multiplication layer of a first semiconductor material, an absorption layer of a second semiconductor material and a field control layer of a third semiconductor material having. The field control layer has a moderate doping of a first type dopant and is intermediate between the multiplication and absorption layers. A central region of the multiplication layer is diffused with a second type dopant which results in a diffused region having a greater thickness in the center than in the periphery of the diffused region.

International Classification:

B01D 15/08

US Classification:

2101982, 2105021, 210635, 210656, 502404

Abstract:

The present invention relates to an asymmetric chromatography media suitable for separations applications, particularly as packed bed, fluidized bed or magnetized bed chromatography media. In certain embodiments, the asymmetric chromatography media comprises asymmetric particles, preferably beads, having at least two distinct, controlled pore size distributions. Preferably one of the distinct pore size distributions is in an internal region of the particle, and the other is in an external region or coating on the particle. These distinct pore size distributions can be modified with uniform or alternatively unique functional groups or mixtures of functional groups. The present invention allows for the control over pore size distribution within an asymmetric porous particle by providing a distinct internal region, preferably in the form of a bead, and a distinct external region, preferably in the form of a coating on the bead.
