The mostly used techniques to improve the coupling efficiency and alignmenttolerance include using micro single lens, micro lens group and lensed fiber.
The enhancement factor strongly depends on the illumination spot size, taper Angle of the probe, and the metal film thickness. The tolerance of the alignment Angle is investigated.
