Open publisher page 0 citations

Abstract

Fabry Perot (FP) and distributed feedback (DFB) laser diode rate equations were augmented to model optical back-reflections. The proposed laser model was implemented and used in simulations to determine the effect of reflected optical power on the performance of directly modulated FP and DFB laser diodes for modulation frequencies spanning near-DC to 10 GHz. The relationship between optical feedback and the laser threshold current and the laser linearity are examined and presented with supporting measurements
