Embodiment 1
[0100] In the present invention, between the light-emitting light-concentrating part including the light-emitting element chip (LD) and the lens, and the socket part including the fiber stub (Fiber stub) and detachably holding the external optical fiber, a rotationally symmetrical shape is provided and maintained. Optical elements with polarization properties on the joint sleeve. First, adjust the positional relationship between the light-emitting concentrating system and the optical fiber ferrule to the quasi-optimum position (the point with the largest amount of light in the XY and R directions, and point G on the extension line of the concentrating point H in the Z direction). The rotation angle of the optical element with polarization characteristics that enables the external optical fiber to obtain a desired amount of light is obtained by rotating the splice sleeve and the optical element with polarization characteristics integrally. And, at this angle, the joint sleeve, ...
Embodiment 2
[0138] In the present invention, a splice sleeve held in a rotationally symmetrical shape is provided between the light-emitting converging section including the light-emitting element chip (LD) and the lens, and the socket section including the fiber ferrule and detachably holding the external optical fiber. Optical elements with polarization properties. Adjust the positional relationship between the light-emitting concentrating system and the optical fiber ferrule to the quasi-optimum position (the point with the largest amount of light in the XY and R directions, and the G point on the extension line of the concentrating point H in the Z direction). The rotation angle of the optical element with polarization characteristics that enables the external optical fiber to obtain a desired amount of light is obtained by rotating the splice sleeve and the optical element with polarization characteristics integrally. Under this angle, the joint sleeve, the light-emitting concentrati...
