In this paper, the dynamic properties of Fabry-Pérot laser diode (FP-LD) transmitters using side-mode injection locking, which are intended to be applied in wavelength-division-multiplexed passive optical networks (WDM-PON) and local area networks (LANs), have been investigated. Both the direct modulation properties and wavelength switching properties of the transmitters have been clarified theoretically and experimentally, as well as the important direct modulation characteristics, such as injection power dependence, side-mode dependence, and wavelength detuning dependence. To confirm the transmission ability, fundamental transmission experiments of the transmitters in both continuous and discontinuous injection cases have been made. The experiments clarified that the error-free transmission was possible in both cases. Falling and rising times during wavelength switching actions in LAN applications have been calculated and measured. A high-speed switching method was proposed in this paper, and the effectiveness of the proposed method has been confirmed theoretically and experimentally.
