Device for compensation of the chromatic dispersion in optical systems with chirped bragg - gratings

摘要

Device for compensation of the chromatic dispersion in optical systems with two chirped bragg - gratings with opposite intrinsic chirp and with means for setting of the chirp of the bragg - grid, characterized in that the device as - integrated optical waveguide structure is formed, in which the bragg - grid (3, 4) to be traveled in succession - integrated optical waveguide (31, 32; 41, 42) are written, wherein the bragg - grid (3, 4) have a linear intrinsic chirp and the means for adjusting the chirp of the bragg - grid (3, 4) in each case a linear temperature gradient to the bragg - grid (3, 4) applying.
