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 density. The present work shows the effect of the injection current on some static characteristics (photon density, carrier density , refractive index, gain margin and optical power) of QWS DFB laser diodes. | ||
