High-performance and low-cost sensors are critical devices for high-throughput analyses of bio-samples in medical diagnoses and life sciences. In this paper, we demonstrate photonic crystal nanolaser sensor, which detects the adsorption of biomolecules from the lasing wavelength shift. It is a promising device, which balances a high sensitivity, high resolution, small size, easy integration, si...
In this paper we studied the focusing effect of electromagnetic wave in the two-dimensional graded photonic crystal consisting of Silicon rods in the air background with gradually varying lattice constant. The results showed that graded photonic crystal can focus wide beams on a narrow area at frequencies near the lower edge of the band gap, where equal frequency contours are not concave. For c...
We propose a novel two state and all-optical controllable switch using DIT, Kerr effect and interaction between quantum dots (QD) and quantum electrodynamics cavity (CQED). The two state and all-optical controllable switch is coupled to photonic waveguide from a rapid nonlinear environment (photonic crystal) and CQED. We consider the nano-crystal are doped to crystal photonic cavity as a 4-leve...
A simple two-layer refractive index sensor based on surface plasmon resonance has been proposed in this work, which evinces high sensitivity for detecting unknown analytes. This design includes hexagonal- and octagonal-shaped air-hole rings, have introduced the first second layers, respectively. By performing amalgamation of different types air holes, gold-coated plasmonic sensing scheme provid...
