  • Abstract
    Single-longitudinal-mode operation under a gain-switched condition, generating 20 ps optical pulses, has been attained in DFB lasers emitting at 1.3 μm wavelength. It has been clarified that Δλ, which is the difference between the DFB wavelength and the gain peak wavelength, plays an important role in stable single-mode operation. The optimum range of Δλ wave found to be in the range from -15 nm to 0 nm
