Drawing:
Two main technical routes of optical fiber coupling:
Fiber bundle coupling method: Fiber bundle coupling method (also known as fiber array coupling method) is a kind of fiber coupling technology used in the early days. It has a simple and clear structure, high coupling efficiency, and the gap of each light-emitting element does not affect the overall beam quality and low cost. This method collimates and compresses the light beams emitted by each light-emitting unit of the LD Bar through the micro-optical system in the fast axis direction, and couples them with the same number of optical fiber arrays one by one, and then bundles the light beams at the exit end of the optical fiber bundle through the optical fiber bundle. .
Micro-optical system coupling method: The micro-optical system shaping coupling method is to collimate, reshape, transform and focus the light beam output by the LD Bar through a micro-optical system (microlens array, microprism array, microlens, etc.) into a single beam In the fiber.
