Abstract :
The performance characteristics of a quasi-single longitudinal-mode Fabry-Perot (FP) laser manufactured by longitudinal modal perturbation of a conventional FP laser are presented. A K factor of 0.67 ns, a linewidth below 41 MHz and a chirped spectral width (20 dB down full width) of 0.56 mn are reported. Such performances and the low cost involved with the manufacturing process should result in more widespread use of such single-mode lasers in various application areas.
