When optical components are reduced to the nanoscale, they exhibit interesting properties that can be harnessed to create new devices. For example, imagine a block of material with thin layers of alternating materials. This creates a periodic arrangement of alternating dielectric constants, forming a "photonic crystal" that is analogous to the electronic crystals used in semiconductor devices. Photonic crystals, along with quantum dots and other devices patterned at the nanoscale, may form the basis for sensors and switches used in computers and telecommunications.

Tutorial on Two Photon Lithography Tool
26 Nov 2018 | | Contributor(s):: Mohammad Mahfuzul Kabir, Varun Ajit Kelkar
Two-photon lithography (TPL) is a nano-scale 3-d fabrication technique. TPL depends upon the two-photon polymerization process, whereby two incident photons of light are absorbed by a precursor material leading to polymerization. The smallest feature size (voxel) achievable in a TPL...
