ABSTRACT
This paper is about the V-cavity tunable semiconductor laser with a 1550â
nm band used as a transmitter to build a wavelength division multiplexing (WDM) optical fiber communication link. In the experiment, a 20â
km optical fiber communication link with a reasonable eye diagram and low bit error rate (BER) transmitted by 40 Gbps can be established. The experimental results show that a single laser can achieve a wavelength tuning range of 25â
nm, reach 32 channels at a 100â
GHz frequency interval, and the average side mode suppression ratio (SMSR) is above 39â
dB. The advantages and application potential of V-cavity tunable semiconductor laser (VCL) for wavelength routing in optical communication networking are verified by experiments.
