A miniature fiber-coupler-based microfluidic system is proposed for trapping of DNA biomolecules. The loop-shaped fiber-coupler is fabricated by using flame tapering technique and integrated in a microfluidic channel. Probe-DNA immobilized on the fiber-co
A terahertz (THz) polarizer and switch structure is proposed based on the phase transition of vanadium dioxide (VO2). When VO2is in the insulation phase, the resonance frequencies of the proposed structure are 1.49 THz and 1.22 THz f
