Title:
WAVELENGTH DIVISION MULTIPLEXING USING CARBON NANOTUBES
Document Type and Number:
WIPO Patent Application WO2005065327
Kind Code:
A3
Abstract:
In a narrow band light source (100), the optical emission wavelength is adjusted and stabilized based upon one or more carbon nanotube ambipolar FETs (104) where electrons and holes combine to emit light at the nanotube bandgap and a component (110) adapted to change and control the nanotube bandgap by physical distortion, bending or chemical and electrical effects. A feedback loop can be included to stabilize or scan the wavelength. In a network using such light sources (100), some of the sources can be held in reserve in case others fail.
