| Abstract(in English) | We develop a high-speed dispersion measurement system, which can measure the transient response of tunable dispersion compensators with sufficient accuracy. This system is based on optical frequency-modulation method and the deviation of optical frequency-modulation is broadened by using a tunable VCSEL (Vertical Cavity Surface Emitting Laser) which can operate in a wavelength range of over 30 nm without mode-hopping. This modification enables us to reduce the measurement error caused by the group-delay ripple and improve the signal to noise ratio. In this paper, we first explain the principle of the optical frequency-modulation method. Then we applied it to the measurement of the transient response of tunable dispersion compensators using temperature-controlled fiber Bragg gratings. |
