Abstract

Calculations of the frequency noise spectra and of the coherence functions between the electrical and the optical noises for a single-mode packaged vertical surface emitting laser(VCSEL) are reported.A rate-equation model for an index guided VCSEL is used, implemented with the electrical noise model including the intrinsic device, the package and external bias network. The extended model works up to the laser relaxation frequency. The amplitude optical noise and its correlation with thefrequency and electrical noises are also analysed. The influence on the calculated quantities of some electrical and laser parameters is evaluated. The results show that generally the frequency noise is correlated with the electrical noise only at low power near the threshold. Comparisons with existing experimental data show good agreement.
