Method and system for pass band flattening and broadening of transmission spectra using grating based optical devices |
摘要 |
A device for expanding an operable wavelength band of an optical component is disclosed. The device has an optical grating configured to receive a wavelength division multiplexed optical signal. The optical grating is configured to separate the optical signal into two wavelength bands separated by a prescribed wavelength difference. The device has a focusing lens system to focus the two wavelength bands onto a receiving surface. The two wavelength bands are separated on the receiving surface by the prescribed wavelength difference in order to expand the wavelength band of the WDM signal.
