Evaluation techniques for semiconductor devices are keys for device development with low cost and short period. Especially, dopant and depletion layer distribution in device is critical for electrical property of the device and is needed to be evaluated. Super-higher-order nonlinear dielectric microscopy (SHO-SNDM) is one of the promising techniques for semiconductor device evaluation. We devel...

We demonstrate the use of a 30-period dielectric stack structure as a highly dispersive device to spatially separate two beams with a 4-nm wavelength difference by more than their beam width. Unlike previous devices, our structure is simple to fabricate and relatively compact. We discuss possible applications of our device within wavelength-division multiplexing systems.

Over the last century a number of techniques have been developed which allow the measurement of the dielectric properties of biological particles in fluid suspension. The majority of these techniques are limited by the fact that they only provide an average value for the dielectric properties of a collection of particles. More recently, with the advent of microfabrication techniques and the Lab...

Considerable modulation ratios are achieved for GaAs multiple-quantum-well reflector modulators grown on Si by inserting an AlAs/AlGaAs dielectric mirror into the device structure. Modulation ratios of up to 4: 1 is attained as the external bias voltage is increased to 9 V and the lC-1HH exciton absorption peak undergoes quantum-confirmed Stark shift. Measurements also indicate that cavity effe...

In this work we report on the characteristics of an electro-optical dielectric-loaded surface plasmon polariton waveguide ring resonator. By doping the dielectric host matrix with an electro-optical material and designing an appropriate set of planar electrodes, we measured a 16% relative change of transmission upon application of a controlled electric field. We have analyzed the temporal respo...

Novel designs of demultiplexers based on photonic crystal fibers (PCF) s and photonic crystal waveguides (PCW) s are presented here. We have considered two types of PCFs and PCWs, namely Dual concentric core PCF, Multicore PCF, PCW with dielectric rods in air and PCW with air holes in dielectric background. Finite difference time domain method (FDTD) is employed to analyze all these devices at ...

We demonstrate the gravure printing of a high-performance indacenodithiophene (IDT) copolymer, indacenodithiophene–benzothiadiazole (C16IDT–BT), onto self-aligned organic field-effect transistor architectures on flexible plastic substrates. We observed that the combination of a gravure-printed dielectric with gravure-printed semiconductor yielded devices with higher mean-effective mobility than...

We develop a theory to study stationary TM-type waves propagating in a nanostructured layer of 2D nonlinear optical metamaterial or plasmonic device. It is assumed that the layer is inhomogeneous and contains non-linear isotropic elemental materials with non-linearity and loss mechanisms, including both linear and non-linear losses. While modeling of the non-linear propagation of the TE-type sc...
