Abstract
This chapter is a treatment of selected optoelectronic devices that illustrate concepts covered in previous chapters. Optical processes in semiconductors are introduced and discussed, including modifications due to quantum confinement in semiconductor devices. Band structure calculations and transfer matrix methods applied to photonic crystals are introduced with a treatment of numerical calculations. Calculations include results using combinations of dielectric or metallic materials to illustrate the techniques. The concept of metasurfaces using V-shaped antennas to deflect optical beams is examined. Applications of electron tunneling using metal–insulator–metal nanostructures for energy harvesting and nonlinear optical processes, especially surface-enhanced Raman scattering, for nanosensing are introduced.
