Abstract
In a semiconductor laser module, a semiconductor laser element is disposed on a side surface of a submount perpendicular to a front surface of a pedestal. The semiconductor laser element, the submount, a lens, and an optical fiber are positioned on the front surface of the pedestal so that laser light emitted from the semiconductor laser element is applied through the lens to a prescribed portion of the optical fiber with high reliability. Positioning of the laser element in the direction perpendicular to the front surface of the pedestal is facilitated, and positioning accuracy is improved, resulting in a low-cost and high-performance semiconductor laser module.
