Abstract
A new, incoherent, optical negative feedback method is proposed and demonstrated for spectral linewidth reduction and optical frequency stabilization of distributed feedback lasers. The spectral linewidth and the optical frequency drift are simultaneously reduced to about 50 kHz and less than 10 MHz, respectively.Keywords
