Analysis of a single-mode DBR laser at 850nm using TWLM
Here, a DBR laser with selective mirror is modeled using the traveling wave laser model and its spectral performance is investigated. The gain medium of the proposed laser is comprised of GaAs and Al0.7Ga0.3As core and cladding, respectively. The modal analysis is carried out to extract the effective index, group index, and the confinement factor of the proposed gain medium at 350 THz for TE polarization. The output power of 18.1dB and 12.23dB are obtained for the proposed FP-DBR and FP lasers at 850nm, for effective index of 3.09RIU, while the output power of 5.25dB and OdB are achieved for FP-DBR and Fabry-Perot cold cavity lasers, respectively regarding the identical condition.
