Abstract
The method of two-photon lithography is used to fabricate GRIN microstructures. Test rectangular structures with sizes 25 × 25 × 3 micrometers were used with varying laser intensity by linear or gaussian distribution in one dimension. The resulting refractive index has been tuned in the range of 0.03. The suggested method can be applied to produce arbitrarily shaped 3D GRIN micro-optical elements.
