Recently, the fabrication of CdSe nanoplatelets became an important research topic. Nanoplatelets are often described as having a similar electronic structure as two-dimensional quantum wells and are promoted as colloidal quantum wells with monolayer precision width. In this paper we show that nanoplatelets are not ideal quantum wells, but cover depending on the size: the strong confinement reg...

waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. optical fibers can also be employed in such systems. besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. in this paper, we introduce two new designs of index-guiding photonic crystal fiber ...
