Trapped particle classification in additive manufacturing
This technology is an improvement to a rapid design approach for designing nanophotonic devices. It is a method of optical positioning and linking (OPAL) using highly focused lasers (sometimes called “optical tweezers”) used for nanofabrication of molecules for devices, drugs, and other nano-metamaterials.
Combined with the previous optical...
