The use of photons to directly or indirectly drive chemical reactions has fundamentally changed the field of nanomaterial synthesis, leading to the emergence of new sustainable laser chemistry methods for manufacturing micro - and nanostructures. The incident laser radiation triggers complex interactions between chemical and physical processes at the interface between solid surfaces and liquid or ...
Background IntroductionTwo dimensional materials have attracted widespread attention due to their atomic level thickness and unique properties, such as high binding energy, tunable bandgap, and new electronic degrees of freedom (valley electronics). They have many application prospects in fields such as microelectronics, nanophotonics, and nanoenergy. Various two-dimensional materials have their o...
In recent years, breakthroughs in the preparation technology of lithium niobate single crystal thin films have greatly promoted the important application of lithium niobate crystals in micro nano optical devices such as optical metasurfaces. However, the high hardness and inactive chemical properties of lithium niobate crystals pose significant challenges to micro nano processing; In addition, con...
The formation of dissipative solitons is influenced by various factors, such as spectral filtering effect and Kerr nonlinearity effect. This interaction leads to the possibility of mode locking on a large range of parameters, generating pulses with completely different types and evolution from conventional physical laws and optical properties, tolerating higher nonlinear effects, and effectively a...
Researchers from the Massachusetts Institute of Technology and the University of Texas at Austin showcased the first chip based resin 3D printer. Their concept verification tool consists of a millimeter sized photon chip that emits a programmable beam of light into resin holes, which solidify into a solid structure when exposed to light.The prototype processor does not have mobile components, but ...
