Abstract :
The spectral linewidth of three types of single-frequency InGaAsP lasers, including a GRIN-rod external coupled-cavity (GRECC) laser, a cleaved-coupled-cavity (C3) laser, and a ridge-waveguide distributed-feedback (DFB) laser, were measured and compared. The narrowest linewidth, 3 MHz at 4.9 mW, was exhibited by the GRECC laser.
