In this thesis, the coherent phonons excited by THz pulses are experimentally demonstrated for the first time in both GaAs and InSb. The resonant excitation using THz pulses enables the coherent control of the lattice ...

Moving from circuit blocks to sub systems with an outphasing transmitter architecture proposed to take advantage of the high output power from the frequency doubler. Through the outphasing mechanism, the PA frequency doubler ...

The phonon density of states and dispersion relation strongly depend on the size and boundary conditions of nanorod. Our work demonstrates the possibility of modifying the phonon transport properties in nanoscale materials ...

The optimized performance of a complete system depends on the efficiency of its building blocks. The presented work, therefore, paves the way towards cost efficient implementation of a high speed optical receiver front end ...

The color rendition properties of the illuminant are quantified by a set of novel Statistical Color Quality Metrics (SCQM), which measure the color rendition properties not only by the ability of the light source to reveal ...

In this work, a TiO₂ simple cubic PC with high dielectric contrast ( > 4:1) is fabricated with a lattice constant of 450 nm, and a newly discovered light-trapping mechanism is demonstrated, which bends light by 90 degrees ...
