Externally amplified spontaneous emission (ASE) injection-locking characteristics and optical data transmission performances of a TO-56 can-packaged Fabry-Perot laser diode (FPLD) with 1% front-facet reflectivity are investigated using a wavelength-division-multiplexing passive-optical network (WDM-PON) system configured by an array-waveguide grating (AWG) based MUX/DMUX filters with channel spacing of 200 GHz. Quasi-single-mode output of such a nearly color-free weak-resonant-cavity FPLD with highest side-mode suppressing ratio of 31 dB is achieved with ASE injection-locking, providing a bit-error-rate (BER) of < 10 -13 at receiving power of -31 dBm and a power penalty of 0.5 dB after 20-km transmission in single-mode fiber with a bit rate up to 1.25 Gbit/s.
