Theoretically, increasing the mode confinement is the way to go to improve the nonlinear efficiency, and we are actively working in this direction [1], but up to know there are still fabrications issues to solve to get low loss, highly confining waveguides with preserved nonlinearities in PPLN. Therefore, we are still intensively studying the...

Formation of domain structure by electron beam irradiation in congruent lithium niobate covered by surface dielectric layer with planar and channel waveguides produced by Soft Proton Exchange (SPE) process has been studied. Formation of domains with arbitrary shapes as a result of discrete switching has been revealed. The fact was attributed to...

Microfluidic separation of magnetic particles is based on their capture by magnetized micro-collectors while the suspending fluid flows past micro-collectors inside a micro-channel. Separation of nanoparticles is often challenging because of strong Brownian motion. Low capture efficiency of nanoparticles limits their applications in...
