We analyze the propagating optical modes in a Silicon membrane photonic crystal waveguide, based on subwavelength-resolution amplitude and phase measurements of the optical fields using a heterodyne near-field scanning optical microscope (H-NSOM). Fourier analysis of the experimentally obtained optical amplitude and phase data permits identification of the propagating waveguide modes, including...
We demonstrate integrated holographic grating filters, that can be designed toward any desired target spectrum. A straightforward design method transforms this target spectrum into a weak effective refractive index variation. The filters are implemented in high-contrast silicon-on-insulator by modulating the width of the shallow etched sides of a ridge waveguide. Measurements show that this is ...
Microwave heating has a wide range of applications in the fields industrial and drying. However, when microwave is applied to thin film, it will be challenging due its low loss large heat dissipation area. In this paper, double-ridged waveguide for thin-film proposed. The double ridge structure employed enhance electric field, thereby increasing power-loss density film. Firstly, waveguide, whic...
We have modeled and numerically simulated the performance of a dielectric-loaded graphene surface-plasmon-polariton (DL-GSPP) waveguide as a biochemical sensing device. In our device, the conventionally used gold layer is replaced with a graphene microribbon for the detection of biochemical molecules. The graphene layer is incorporated to minimize ohmic losses and to enhance the adsorption of b...
