Integrated light engine structure and manufacturing method thereof

The invention discloses an integrated optical engine structure and a manufacturing method thereof, the integrated optical engine structure comprises a substrate and a component arranged on the substrate, the component comprises an optical fiber array, a lens array, a PD array and a TIA transimpedance amplifier, the lens array comprises a plurality of lenses, the lenses are spherical lenses with the same diameter as a first positioning section of an optical fiber, the plurality of lenses are respectively arranged in a plurality of V-shaped grooves, and the first positioning section of the optical fiber is arranged in the V-shaped grooves. And the signal receiving surfaces of the plurality of photoelectric detectors are respectively opposite to the notches of the plurality of V-shaped grooves. The spherical lens is adopted, the outer diameter of the spherical lens is the same as that of the first positioning section of the optical fiber, the V-shaped groove structure ensures that the optical axis of the optical
