Abstract
A fiber coupling device (100) includes the following components: a wedge plate (102) for receiving light and refracting the light in a predetermined direction, a condenser lens (104) for collecting the light refracted by the wedge plate (102); and an optical fiber (107) having an incident surface for receiving the light collected by the condenser lens (104). The wedge plate (102) is held rotatable around the optical axis (200) of the light incident on the wedge plate (102). The light refracted by the wedge plate (102) and collected by the condenser lens (104) is incident on a different point on the incident surface depending on the rotation angle of the wedge plate (102).
