Abstract :
An overview of research activities in China on the following optical communications devices is presented: quantum-well semiconductor lasers; distributed feedback laser diodes; wideband, tunable, narrow-linewidth, external-cavity laser diodes, semiconductor and doped-fiber amplifiers; laser-diode-pumped solid state and single-crystal fiber lasers; doped fiber ring lasers, optical modulators; switches; bistable devices; experimental wavelength-division-multiplexed (WDM) systems; and time-division photonic switching systems. The most important of these technologies are highlighted with respect to demonstrated achievements in China. The potential uses of these technologies in future telecommunications systems are discussed.<>
