摘要：

A mixed digital-to-analog (DIA) high-speed circuit board capable of driving a tunable super structure grating distributed Bragg reflector (DBR) laser is developed. The circuit is used to control the laser over a 20-nm tuning wavelength range with 0.1 nm resolution. Three control currents are preprogrammed into an electrically erasable/programmable read-only memory (EEPROM) look-up table for each wavelength. Upon receiving a differential logic control signal, the circuit tunes the laser to the specified output wavelength within 500 ns, The longterm repeatability of the tuned laser output wavelength shows drift below +/-0.02 nm with greater than 100 h of operation.
