Abstract
Quarterly wavelength shifted (QWS) distributed feedback (DFB) laser structures are commonly referred to be associated with high mode selectivity, zero-frequency detuning and small threshold current density. The present paper compares different asymmetric QWS structures in the threshold regime, the results being summarized to show their influence on the emission laser characteristics.
