摘要	To provide a semiconductor laser diode and a semiconductor optical amplifier and an optical communication device incorporating the semiconductor laser diode or the semiconductor optical amplifier which enable low power consumption and high optical output. A semiconductor laser diode according to an embodiment of the present invention is a semiconductor laser diode 100 comprised of an active waveguide, the active waveguide including a first waveguide 11a that supplies a plurality of modes including a fundamental mode; and a second waveguide 12a that is wider than the first waveguide 11a and supplies a multimode, wherein the fundamental mode is provided as an oscillation light oscillated from the active waveguide.
其他摘要	提供半导体激光二极管和半导体光放大器以及包含半导体激光二极管或半导体光放大器的光通信装置，其能够实现低功耗和高光输出。根据本发明实施例的半导体激光二极管是包括有源波导的半导体激光二极管100，该有源波导包括提供包括基模的多个模式的第一波导11a;第二波导12a比第一波导11a宽并提供多模，其中基模作为从有源波导振荡的振荡光提供。
主权项	A semiconductor laser diode comprising an active waveguide where a fundamental mode waveguide that supplies only a fundamental mode is not provided, the active waveguide comprising: a first waveguide that supplies a plurality of modes including a fundamental mode and a mode other than the fundamental mode; and a second waveguide that is wider than the first waveguide and supplies a multimode, wherein the fundamental mode is provided as an oscillation light oscillated from the active waveguide.
