Paper Abstract

According to the wavelength tuning characteristic of widely tunable sampled grating distributed Bragg reflector (SG-DBR) lasers, a kind of wavelength control system is developed. A look-up table, the file including data of picked operation points, is established to store the relationship between lasing wavelengths and tuning currents for each SG-DBR laser in the system. By rapidly looking up the look-up table and providing the corresponding driving currents, the particular lasing wavelength of SG-DBR laser is obtained. Wavelength tuning experiments have been done with eight SG-DBR lasers, and the results show that this system has high precision of wavelength control.
