Paper Abstract

A method of measuring the group time-delay of chirped fiber grating g(CFG) is presented in this paper. This approach is based on mode-mocking technique. An F-P cavity LD and a linearly CFG under test compound together to be an external cavity laser. Group time-delay can be investigated by measuring adjusted RF frequency and corresponding lasing wavelength.
