The present application provides an adjustment device and method for fast and efficient coupling of spatial light, which relate to the technical fields of photoelectric detection and optical communication equipment. Wherein, the light source is arranged on the adjustment platform, and the collimating lens is arranged on the light path of the light emitted by the light source; the beam splitter can divide the light collimated by the collimating lens into the first beam and the second beam; the first focusing lens can After focusing the first beam of light, it is transmitted to one end of the single-mode fiber, and the other end of the single-mode fiber is connected to the fiber splitter. The efficiency of spatial light coupling to the single-mode fiber can be estimated through the fiber splitter; the second focusing lens is located at the second On the optical path of the two beams of light; the imaging device is used to image the focused second beam of light; the controller can control the adjustment platform to adjust the spatial position and position of the light source according to the imaging information transmitted by the imaging device and the power information transmitted by the optical power meter The emission angle realizes the automatic adjustment of the space light source and efficient coupling to the single-mode fiber, saving the adjustment time of the space light coupling to the single-mode fiber.
Description
technical field [0001] The present application relates to the technical field of photoelectric detection and optical communication equipment, in particular to an adjustment device and method for fast and efficient coupling of spatial light. Background technique [0002] At present, optoelectronic technology is widely used, which puts forward high requirements for the spatial transmission of light beams. Single-mode optical fiber transmission is being widely used because of its strong anti-interference, high security and invariant spatial mode characteristics. [0003] The existing general technology for coupling spatial light beams to single-mode optical fibers is to first collimate the divergent light output by the light source with a collimating lens, and then use a high-magnification microscope objective lens to focus the collimated light onto the end face of the optical fiber to ensure that it is transformed by the lens. The final optical spatial mode is matched with the...
