Numerous optical phenomena and applications have been enabled by nanophotonic structures. Their current fabrication from high refractive index dielectrics, such as silicon (Si) or gallium phosphide (GaP), pose restricting challenges while metals, relying on plasmons thus exhibiting ohmic losses, limit the achievable applications. An emerging class of layered, so-called van der Waals (vdW), crys...

Transition metal dichalcogenides (TMDs) attract significant attention due to their exceptional optical, excitonic, mechanical, and electronic properties. Nanostructured multilayer TMDs were recently shown be highly promising for nanophotonic applications, as motivated by exceptionally high refractive indices optical anisotropy. Here, this vision is extended more sophisticated structures, such p...

In this chapter, we will discuss the impact that photonics have on photovoltaic (PV) manufacturing. The broad field of photonics is now commonly thought to encompass classical optics (Hecht, 2001), nanophotonics (Joannopoulos et al., 2007), and metamaterials (Cai and Shalaev, 2009). Over the last few decades, photonic technology has become an increasingly integral part of PV manufacturing, both...

We show GHz modulation in a 2.5 microm radius silicon micro-ring, with only 150 mV peak-peak drive voltage and an electro-optic modal volume of only 2 microm(3). The swing voltage and the micro-ring modulator are the smallest demonstrations so-far in silicon. The presented approach lays the ground work for a new class of high speed low voltage modulators enabling, seamless integration of nanoph...

Nanolithography techniques providing a good scalability and feature size controllability are of great importance for the fabrication integrated circuits (IC), MEMS/NEMS, optical devices, nanophotonics, etc. Herein, cost-effective, easy...

Abstract Nanophotonics inverse design is a rapidly expanding research field whose goal to focus users on defining complex, high-level optical functionalities while leveraging machines search for the required material and geometry configurations in sub-wavelength structures. The journey of begins with traditional optimization tools such as topology heuristics methods, including simulated anneali...
