Monolithic and external-cavity mode-locked diode lasers (Mode-Locked Laser Diodes: MLLDs) are highly stabilized by means of electrical or optical signal injection incorporating a compact device module packaging. These MLLDs have potential applications in ultrahigh-speed optical communication and optical measurement systems. The MLLDs developed fully satisfy the requirements in a light source for the optical time division multiplexing (OTDM) communication scheme at 100 Gb/s rate. Instead of electrical hybrid mode-locking, subharmonic optical pulse injection can stabilize the MLLD operating at over 100 GHz. This technology will be useful for the generation of millimeter and sub-millimeter electromagnetic waves with optoelectronic conversion. Another notable feature of highly stable MLLDs is to provide pump and probe optical measurements with a simple system excluding mechanical optical-delay, that is to say the optical sampling. This optical sampling enables to observe 100 Gb/s rate optical data eye-pattern as well as precise temporalresponse of optical materials.
