| Abstract(in English) | The GaInNAs has an ideal band-lineup as compared with conventional long-wavelenth acitve materials. We investigated TQW (triple quantum well) structure in terms of high speed operations. In order to improve the crystallinity of GaInNAs-TQW, an Al-free MBE eptaxial system was developed and a TQW structure was optimized. As a result, low threshold current density of 468A/cm^2 is obtained, which is almost the same as the lowest one grown by MBE. Moreover, it is demonstrated that the record low threshold current of 4.3mA is achieved in long-wavelength, 1.29μm, GaInNAs-TQW RWG lasers. In addition, 40-Gb/s direct modulation of the laser is confirmed at 5℃. |
