Abstract

In this paper, the injection locking technique is investigated by applying the external lightwaves to a Fabry-Perot laser (FP-LD). The static and dynamic characteristics are studied in detail, which include optical spectrum analysis such as the output intensity, the side mode suppression ratio (SMSR), and the mode selection characters, as well as the dynamic linewidth suppression, the wavelength detuning speciality, and the frequency responses. With proper adjustments, the maximum SMSR of 50 dB is obtained, and the frequency response of the injection-locked FP-LD has been improved with the proper wavelength detuning. Besides, we concentrate on the applications of the injection locked FP-LD in wavelength-division-multiplexing passive optical network (WDM-PON) systems, and a protection scheme for WDMPON transmitters spare function is proposed and demonstrated at the same time. Compared with the conventional methods, this proposed architecture provides a cost-effective and reliable protection scheme employing a common FPLD. In the experiment, a 1:36 protection capability was implemented, in the wavelength range from 1537.4 nm to 1565.4 nm.
