TY - JOUR ID - TI - EFFECT OF INJECTION CURRENT ON SOME STATIC CHARACHTRISTICS OF QUARTERLY WAVELENGTH-SHIFTED DISTRIBUTED FEEDBACK LASER DIODES AU - Mohammed D. Noori PY - 2012 VL - 2 IS - 1 SP - 56 EP - 66 JO - Journal of Education for Pure Science مجلة التربية للعلوم الصرفة SN - 20736592 AB - 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.
