英文摘要A laser diode module provides methods for coupling laser light and optical fiber which achieve a higher coupling efficiency than conventional methods and is cheaper and easier to assemble without losing conventional high-frequency power supply function. In a laser diode module, a high-frequency electric line 11 to a laser diode is located on the upper surface of a photodiode carrier 4 for supporting a photodiode 3; the photodiode carrier 4 is large with a trapezoidal shape. This shape prevents the surface of the photodiode 3 from returning to the laser diode reflected light emitted from the rear of the laser diode A spherical convexo-plane lens 27 is located so that its spherical surface faces the laser diode 1 and is held on a lens holder 22 with a cylindrical hole at an optimum angle to a slant end of an optical fiber core 23 so that a center of curvature 29 of the spherical surface is on an optical axis 19 of laser light which is collimated by a collimating lens 7.
