摘要
Provided is a semiconductor laser diode. The semiconductor laser diode (100a) includes a first material layer (120), an active layer (130), and a second material layer (140), characterized in that the semiconductor laser diode includes: a ridge waveguide (200), which is formed in a ridge shape over the second material layer (140) to define a channel (180) defined so that a top material layer (143) of the second material layer (140) is limitedly exposed, and in which a second electrode layer (170) which is in contact with the top material layer (143) of the second material layer (140) via the channel (180) is formed; and a first protrusion (210), which is positioned at one side of the ridge waveguide (200) and has not less height than that of the ridge waveguide (200).
