英文摘要 | PURPOSE:To enable a semiconductor laser with monitor to be easily coupled to any optical fibers, by employing a specific structure in which a separating trench is formed with the sidewall thereof on the side of a monitor section in a slope-shape, and the emitted laser beam from a laser section is reflected by the sloped sidewall of the trench to be output. CONSTITUTION:A laser section 8 having a stripe-shaped current injecting region 5, and a monitor section 9 are together monolithically integrated in the same substrate 1, with the laser section 8 and the monitor section 9 being electrically separated each other. A trench 10 for separation is formed with the sidewall 11 on the side of the laser section perpendicular to a p-n junction while the trench being formed with the sidewall 12 on the side of the monitor section inclined at 40-50 deg. to the p-n junction. As a result, the emitted laser beam 14 from the laser section 8 is reflected by the sloped sidewall 12 on the side of the monitor, and thus the reflected laser beam 14 is emitted outward with being perpendicular to the p-n junction, thereby the semiconductor laser with monitor can be easily coupled to any optical fibers. Moreover, since a reflecting film 16 with high reflectance is formed on the far-end surface, the threshold current of the laser can be effectively reduced. |
