A novel polarization channel drop filter (PCDF) based on two-dimensional (2D) photonic crystals (PCs) is presented. It consists of two line defect waveguides and two point defect micro-cavities. In the line-defect waveguides, the transverse-electric (TE)
In this work, Pr3 was introduced into Nd3 -doped tellurite glass with composition TeO2-ZnO-Na2O-Nb2O5 to achieve broadband near-infrared emission. A broadband fluorescence emission ranging
We analyze the properties of a dual-beamtrap of orthogonally intersecting beams in the geometrical optics regime. We derive analytical expressions for the trapping location and stability criteria for trapping a microparticle with uncollimated Gaussian bea
