Abstract

A photoelectric converter comprises a supporting plate, a light transmission main body, a plurality of first lenses, a plurality of second lenses and a plurality of optical fibers arranged on the light transmission main body. The light transmission main body comprises a first surface and a second surface opposite to the first surface. The plurality of first lenses are convexly arranged on the first surface, an optical fiber installation groove is arranged on the second surface and comprises a side surface, and the plurality of second lenses are convexly arranged on the side surface. The optical axes of the first lenses and the optical axes of the corresponding second lenses are located on the same plane, and the plurality of optical fibers are arranged in the optical fiber installation groove. The photoelectric converter can achieve accurate coupling of the optical fibers and the second lenses simply by arranging the optical fibers into the optical fiber installation groove, and is simple in structure and low in manufacture cost.

Description

technical field [0001] The invention relates to the field of photoelectric conversion, in particular to a photoelectric converter. Background technique [0002] A general photoelectric converter includes a laser diode (Laser Diode), a first light transmission element, a second light transmission element coupled with the first light transmission element, and a photodiode (Photo Diode). After the laser diode emits an optical signal, the optical signal enters the first optical transmission element, is transmitted through the second optical transmission element, and finally enters the photodiode. The optical signal is converted into an electrical signal by the photodiode, thereby achieving the purpose of photoelectric conversion. [0003] The first light transmission element and the second light transmission element are generally coupled through a lens and an optical fiber, the lens is mounted on the first light transmission element, and the optical fiber is mounted on the secon...
