| Abstract(in English) | Using semi-insulating blocking layer, low parasitic capacitance was obtained for 1.3 μm tapered thickness waveguide lasers, which have narrow beam divergence and allow us high optical coupling to a optical fiber, without deterioration of static characteristics such as threshold current and beam divergence. This low parasitic capacitance reduced the turn-on jitter under zero-bias-voltage modulation and realized 156 Mb/s, 40 km penalty-free transmission under zero-bias-voltage modulation at 85℃. Furthermore, by high-reflection coating to both facets and optimizing the gain region length, low threshold currents of 3.2 mA at 25℃ and l0.5 mA were obtained for 320 μm long lasers. These values are the lowest among previous reported spot-size transformer integrated lasers, to our best knowledge. |
