CHANNELIZED DISPERSION COMPENSATION MODULE |
摘要 |
There is disclosed an optical device for dispersion compensation of channels within a predetermined wavelength band, comprising: a waveguid-ing structure; and a grating structure formed in said waveguiding structure; characterized in that said grating structure has a Bragg frequency profile that is divided into contiguous periods, wherein the Bragg frequencies within each period vary between a lower Bragg frequency and an upper Bragg frequency, said lower and upper Bragg frequencies for each period both corresponding to wavelengths outside of said predetermined wavelength band.
