Twisted layers of α-MoO3 support phonon polaritons whose propagation can be adjusted by the twist angle, a concept known as 'twistoptics'. Although emergent in the field of nano-optics, the application to heat transfer has lagged behind, p...
Vortex Lasers [0.03%]
涡旋激光器
A vortex beam at eye-safe band is emitted from a solid-state laser resonator. Such beam carries orbital angular momentum and is employed to sense the spinning cyclone via the rotational Doppler effect. As an ideal class of vortex sources, s...
