Title:
APPARATUS FOR DISPERSION COMPENSATING A SIGNAL THAT PROPAGATES ALONG A SIGNAL PATH
Document Type and Number:
WIPO Patent Application WO2003079585
Kind Code:
A3
Abstract:
Apparatus for dispersion compensating a signal (18) that propagates along a signal path (19), which apparatus comprises a grating (1) and a tuning means (2). The grating (1) is characterized by a wavelength operating range (3) and a group delay (4) that varies with wavelength (5), wherein the group delay (4) is equal at a plurality of pairs of wavelengths (6), (7) that are separated within the wavelength operating range (3), and wherein the grating (1) reflects each wavelength pair (6) from the same region (8) of the grating (1), and different wavelength pairs (7) from different regions (9) of the grating (1).
