Abstract

The invention relates to coupling equipment for area array type light source beam splitting, and a coupling mode thereof, and belongs to the technical field of integrated optics. The equipment comprises an LED light source, a PLC chip, an adhesive, a multi-channel optical fiber array, a bare fiber adapter and an optical power meter. The LED light source is adjustably fixed to the left side of thePLC chip through a left adjusting frame, the right side of the PLC chip is connected with the multi-channel optical fiber array in an adhesive mode through an adhesive, the multi-channel optical fiberarray is installed on a right adjusting frame, the multi-channel optical fiber array is connected with the optical power meter through a bare fiber adapter, the PLC chip is 0 * N chips, and the 0 * Nchips is N output opposite end waveguides, wherein N is a natural number. The numerical value detected by the optical power meter is converted into the corresponding loss value, so that whether coupling succeeds or not is determined, and the equipment and the mode has a wide application prospect.

Description

technical field [0001] The invention relates to a coupling device for beam splitting of an area-array light source and a coupling method thereof, belonging to the technical field of integrated optics. Background technique [0002] At present, the beam splitting of surface light sources is usually done by using physical methods, such as interference or diffraction, and finally realizes the beam splitting of surface light sources, or divergent light sources. [0003] In some special occasions, we need to divide the surface light source into various split beams. The traditional method cannot obtain a uniform beam, and it is also difficult to obtain light of various proportions. But using the 0×N structure in our PLC, we can design the split beams we want. [0004] The beam splitting of the surface light source has not been ideal, and the beam splitting effect obtained is relatively general. So we need to use this 0×N chip. The output end is the same as most PLCs, but the inp...
