英文摘要 | A DFB laser with improved loss grating is disclosed. The grating contains periodically patterned first and second semiconductor layers that are embedded in semiconductor material of composition selected to provide relatively low loss for the laser radiation. The composition of the first layer is selected to provide a relatively high refractive index and loss for the laser radiation, and the composition of the second layer is selected to provide relatively low refractive index and loss for the laser radiation. The thicknesses of the first and second layers are selected such that the real part of the coupling constant | kappa '| is less than the imaginary part of the coupling constant | kappa ''|. In preferred embodiments | kappa '|=0.5| kappa ''|, even=0.2| kappa ''|. |
