Room Temperature Luminescent Erbium Oxide Thin Films For Photonics
US Patent:
6846509, Jan 25, 2005
Filed:
Nov 21, 2001
Appl. No.:
09/991438
Inventors:
Kevin M. Chen - Santa Clara CA, US
Lionel C. Kimerling - Concord MA, US
Lionel C. Kimerling - Concord MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
B05D 302, B05D 512, C23C 1400
US Classification:
427 66, 427 74, 4271263, 427166, 427380, 20419215, 20419226
Abstract:
A system for producing Erbium Oxide thin films with increased photoluminescence. The system includes a depositing stage for forming Erbium Oxide molecules by reacting Erbium sputtered atoms with Oin a gas phase and creating the Erbium Oxide thin film by depositing the Erbium Oxide molecules on a substrate coated with Silicon Oxide. The system further includes an annealing stage for annealing the Erbium Oxide thin films by utilizing a low temperature treatment for a specified amount of time and temperature followed by a high temperature treatment for another specified amount of time and temperature, wherein the crystallinity of the thin films has improved.
Tunable Chromatic Dispersion Compensation
US Patent:

Filed:
Jun 25, 2002
Appl. No.:
10/178965

Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
G02B 6/26
US Classification:
385 15, 385129, 385130
Abstract:
A system for dispersion compensation is provided including a plurality of optical cavities with each including a specific resonant frequency and resonant linewidth. At least one coupling element interconnects the optical cavities. The at least one coupling element defines the coupling strength between the cavities. The optical cavities are interconnected with the at least one coupled element that forms a multi-cavity structure. The multi-cavity structure generates appropriate dispersion properties for dispersion compensation purposes.
