Temperature sensitivity of oscillation wavelength in 1.3 /spl mu/m-GaInAsP/InP quantum-well semiconductor lasers

Characteristics of optical sources for access networks are required to be insensitive to the environment temperature change. In a relatively long-haul (> 10 km) and high bit-rate (>100Mb/s) transmission system, the effect of dispersion of optical fiber could not be negligible. Therefore, the stability of the oscillation wavelength to the temperature change could also be required. In this paper, we experimentally examined the temperature sensitivity of the oscillation wavelength in 1.3 /spl mu/m GaInAsP-InP QW semiconductor lasers.
