Micro optic for coupling a semiconductor laser to an optical fibre.

摘要

A micro optic (L2) for coupling a semiconductor laser (1) to an optical fibre (F2), for which the light rays reflected by this microlens (L2) do not impede the operation of the laser. The lens (L2) is bonded to the end of the fibre (F2) and the normal to the plane of intersection between this lens (L2) and the fibre makes an angle ( theta ) with the axis z of the fibre. Thus the rays reflected by this interface (P2) pass outside of the exit face (Fs) of the laser (1). Application to optical telecommunications. <IMAGE>
