| Abstract(in English) | The 1.3 μm wavelength InGaAlAs directly modulated semiconductor laser is a promising candidate as a high-speed semiconductor light source with a low power consumption for future transmission systems beyond 100 Gbit Ethernet. In this study, the internal temperature increase induced by the injected current of a ridge laser and a buried heterostructure (BH) laser were estimated by simulating the heat distribution in the cavity and evaluating the fabricated devices. As a result, the temperature increase with the BH laser was about 5°C less than with the ridge laser. Next, the reduction in the driving current was also evaluated by comparing the fabricated ridge laser and a BH laser. The driving current of the BH laser for an optical output of 15 mW was about 11 mA less than with the ridge laser. The main reasons for the current reduction are thought to be the strong current confinement and the high heat dissipation of the BH structure. In addition, it is also revealed that the current reduction realized thanks to the heat dissipation effect of the BH laser represents about 20% of the total reduced driving current. |
