摘要：

A continuous wavelength tuning range of 5.4 nm is obtained for a three-section DBR laser by applying one control current in both forward and reverse bias direction. In the reverse direction no significant linewidth broadening is seen due to the absence of injection-recombination shot noise, and a linewidth of less than 3 MHz is obtained over a wavelength span of 1.8 nm. The minimum linewidth observed is 580 kHz.
