摘要： An assembly for combining the outputs from a group of n single mode optical fibres on to the photosensitive surface of a photodetector (1) has an adiabatically tapered bundle (2) of fibres (3) the small end of which is fusion spliced to one end of a length (4) of multimode fibre whose other end is optically coupled with the detector (1) by means of a lens (5).
