Abstract
We report compact graded refractive index lens which can be fusion-spliced to optical fibers by using sol-gel method. We developed optical fiber condenser which can make beam-waist diameter smaller than mode field diameter of simgle-mode fiber, and the condenser has low chromatic dispersion, difference of focal distance is only 6.5 microns between 785nm and 1550nm. We also manufactured a wavelength conversion module and SHG normalized conversion efficiency was 478%/W.
