Ambient light alters refraction in 2D material!

Optical materials that can change the refractive index are needed for emerging applications like virtual reality, 3D displays, optical computers, and LiDAR. However large changes in refractive index and fast response are hard to find in common optical materials. We investigated a new class of material based on strong correlations and discovered their large change…

Novel thermal light source using unconventional quantum physics!

Thermal light sources are necessary for many applications, especially in the infrared. Their design in the past has relied mainly on classical electromagnetics. We instead propose using quantum optics to describe and design thermal sources. Quantum description allows designing the thermal source as a many-resonator system, unlike the classical approach. Many-resonator system brings in new…

Aligned carbon nanotubes tame thermal radiation!

Refractory nanophotonics, or nanophotonics at high temperatures, can revolutionize many applications, including novel infrared sources, ultrahigh density data storage, innovative chemical sensing techniques, and waste heat recovery. In particular, extremely anisotropic optical materials stable at high temperatures are very interesting and promising for revolutionary applications. However, the lack of such materials limits the scope of…
