Abstract
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
200GHz. Quasi-single-mode output of such a
nearly color-free weak-resonant-cavity FPLD with highest side-mode
suppressing ratio of 31dB is achieved with ASE
injection-locking, providing a bit-error-rate (BER) of $<10^{-13}$ at receiving power of $-$31dBm 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.
