dc.description.abstract | In this work we numerically calculate the linewidth of a single–mode monolithic Semiconductor Ring Laser (SRL) operating in the unidirectional regime. A new expression for the SRL linewidth is derived from the conventional Henry’s formula, and the importance of different physical parameters is discussed. In particular, the linewidth is mainly determined by the SRL diameter, because the waveguide bending loss have a very strong dependence on the diameter. We show that circular SRLs with diameter smaller than 180 µm are unlikely to be operated CW. As a general rule, the linewidth decreases for increasing SRL diameter, and it varies from 15 MHz for 200 µm diameter down to 1 MHz for 2000 µm diameter. | es_ES |
dc.description.sponsorship | We have numerically analysed the performance of a monolithic Semiconductor Ring Laser with a circular cavity. Based on the obtained results, optimum device design rules have been identified, with the purpose of either reducing the threshold current, or increasing the emitted power. The linewidth of the SRL has been calculated by adapting the Henry’s formula to the case of CW unidirectional operation. Calculated values for the linewidth lie between 1 MHz and 14 MHz, and show a dependence on the device radius. Large radius SRLs may exhibit linewidths well below 1 MHz if proper design rules are adopted, while smaller radius devices are not likely to have very narrow linewidth. | es_ES |
