Abstract :
We introduce a new method to make gradient index (GRIN) lenses and GRIN lens arrays by exposing diffusion-driven photopolymers using a low-power CW laser. By changing the size and power of the laser beam and the exposure time, the index profile of the GRIN lens can be controlled. A novel feature of this process is that the polymer can be cast on both sides of a micro-optic, followed by exposure and diffusion to develop perfectly aligned lenses.
