Abstract
An optical fiber coupling system is provided which minimizes beam loss. The system includes a substrate with a laser beam emitting unit attached at one end, a first fine lens which focuses or collimates a vertical beam emitted by the laser beam emitting unit, a set of second fine lenses which focus or collimate a horizontal beam emitted by the laser beam emitting unit, and a beam output unit which outputs the beam focused or collimated by the first and second fine lenses. This arrangement reduces an alignment error associated with this type of optical system and improves a degree of beam focus. Additionally, the optical fiber coupling system can be made compact and available for mass-production.
