Abstract : the theoretical investigation of the coupling efficiency of a laser diode to a single mode fiber via a hemispherical lens on the tip of the tapered fiber in the presence of possible transverse offset and angular mismatch is reported . without the misalignment , coupling efficiency increases with the decreasing of taper length . with the misalignment , this relation is that the coupling efficiency decreases with each kind of offset
