Study on raised-cosine chirped sampled fiber Bragg grating for dispersion compensation applications
In this paper, the transfer matrix method based on the coupled mode theory is presented to analyze the raised-cosine chirped sampled fiber Bragg grating. This filter is proposed for the purpose of dispersion compensation in wavelength division multiplexing systems.
Simulation results show that five channels can be obtained in a bandwidth of 0.6 nm, with the dispersion of -1400 ps/nm. The wavelength spacing between two neighboring channels is 0.8 nm.
