... . It also demonstrates that ring resonators provide narrow linewidth filters with a large extinction ratio, making them sensitive to small-parameter variations. Strong optical confinement in rings/disks/spheres cavities ( Vahala, 2003 ) allow strong energy-matter interactions in compact device areas ( Van...

... in electronic, transport, optical, thermal, and ferroelectric properties and show how first-principles modeling help us gain microscopic insights into the mechanisms at the atomic scale. Finally, in Sec. 2.4 , we conclude. Kohn–Sham DFT has few advantages. It is numerically less demanding compared to the wave...

... The nonlinear optical contrasts excited by ultrafast lasers enable in vivo imaging and time-domain spectroscopy. Although the signals are detectable by photomultiplier tubes, the nonlinear optical contrasts of the biomedical tissues are weak for some investigations. Besides, the molecular...

... treatments. Figure 2.1 shows how measurements (spectroscopy, imaging) can be interpreted by theoretical models of light transport to specify tissue optical properties, which are then (1) interpreted as biological parameters to inform clinical decisions and (2) used to specify dosimetry of phototherapy/laser...

... by the a_n and b_n coefficients, respectively, most techniques exposed thus far do not actually measure AOM directly, but rather the total scattering or extinction, i.e., a superposition of the fields radiated by magnetic and electric modes. Consequently, most of these optical characterizations usually require...

.... During the extinction spectroscopy experiments, the mechanical actuation of the sample was realized by exploiting a homemade traction machine [Fig. 10.3(d) ], able to stretch it in a controllable and reproducible way. Results of these experiments considering several stretching steps (0%, 8%, 13%, and 19...
