Title:
【発明の名称】異なる波長を有して共に送信される光信号の分散を補償する方法
Document Type and Number:
Japanese Patent JP2002540481
Kind Code:
A
Abstract:
The present invention is directed to an economical approach for compensating for the dispersion of optical signals having different wavelengths.In accordance with the present invention, photonic crystals (K1-Kn) are positioned on a common optical waveguide (2). In this context, each photonic crystal (K1-Kn) is tuned to reflect or deflect the signals of one wavelength and to transmit the signals of other wavelengths, unattenuated. The specific arrangement of the photonic crystals (K1-Kn) on the waveguide (2) and the specific arrangement of the deflecting elements in the photonic crystal are defined, in the process, as a function of the dispersion to be compensated for between the individual wavelengths.The approach of the present invention makes it possible to assemble permanently set or controllable photonic dispersion compensators of a high quality, which are approximately 1000 times shorter than conventional diffraction gratings.
