Abstract
A novel wavelength measurement method wherein an optical pulse is launched into a dispersive medium with known dispersion properties, such as a dispersion compensating fibre or a dispersion compensating Bragg grating. The specific wavelength of the dispersion-induced light beam is obtained by measuring the propagation time delay through the dispersive medium and relating that propagation time to the calibrated dispersive medium.
