Abstract
A blue light pickup was implemented on - a - chip using leaky mode waveguide. It successfully coupled out the propagating beam keeping the height smaller than 2 mm including objective lens as well as beam shaping elements. The pickup showed Gaussian-like intensity distribution of which efficiency is simulated as 99% over the coupling length of 1 mm at the wavelength of 405nm.
