Thermal emission from a hot body is inherently challenging to control due to its incoherent
nature. Recent advances have shown that patterned surfaces can transform thermal …

Circularly polarized light sources with free-space directional emission play a key role in
chiroptics, spintronics, valleytronics and asymmetric photocatalysis. However, conventional …

C points, circular polarization in momentum space, play crucial roles in chiral wave
manipulations. However, conventional approaches of achieving intrinsic C points using …

Subambient daytime radiative cooling enables temperatures to passively reach below
ambient temperature, even under direct sunlight, by emitting thermal radiation toward outer …

Optical metasurfaces have revolutionized analog computing and image processing at
subwavelength scales with faster speed and lower power consumption. They typically …

We review the physics and some applications of photonic structures designed for the
realization of strong nonlinear chiroptical response. We pay much attention to the recent …
