Thermal analysis of an SOA integrated in SG-DBR laser module

We proposed a novel temperature-dependent model of an SOA integrated in SG-DBR laser module based on finite element method (FEM). Static and transient temperature distributions of the integrated module are simulated by numerically solving the thermo-optical coupling equations. Phenomenon of thermal crosstalk was conspicuously observed. Furthermore, thermally induced wavelength drift of the module was obtained by using a temperature-dependent dynamic transfer matrix method (DTMM) based optical model. Thermal effects on optical output properties of the module were observed. Wavelength drift induced by thermal transients in the SOA is as large as 39 pm.
