Abstract
A photoelectric converter for optical signals includes a laser diode for emitting the optical signals, an optical transmission module for transmitting the optical signals, and a photo diode for converting the optical signals to electrical signals. The optical transmission module includes lenses oriented at ninety degrees from each other, with total internal reflection between the lenses, and optical fibers coupled with the lenses. The photoelectric converter has a high coupling precision between the lenses and the optical fibers, and the loss of optical signals is minimized.
