Abstract
A large and red-shifted FM response and a spectral linewidth of a few megahertz were obtained in a two-active-section MQW DBR laser. It is found that the FM efficiency can be enhanced by using the inhomogeneity in alpha parameters with a high threshold current density device and that there is a tradeoff in the relationship between spectral linewidth and FM efficiency.
