Research Progress
Laser field can not only carry spin angular momentum (SAM) but also orbital angular momentum (OAM). The latter usually leads to a vortex beam profile, which is accomplished using the Laguerre-Gaussian mode.2020-02-14
Formamidinium (FA) perovskites have exhibited outstanding optoelectronic properties in efficient solar cells and light-emitting diodes. However, their development on nanolaser application has rarely been explored, especially the up-conversion lasi...2020-02-12
In a recent study, a team from Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress on radiation resistant YDF. Related work was published on Optical Materials Express.2020-02-12
The total angular momentum (TAM) of light can be separated into spin and orbital parts of the angular momentum (SAM and OAM). 2020-02-06
Since the aggregation-induced emission (AIE) material was found by the Tang research group in 2001, different kinds of AIE materials have subsequently been developed by many research groups. However, their main applications are only in optoelectri...2020-02-05
The interlayer interaction is vitally important for the layer-dependent properties, such as band structure, carrier mobility, and thermal conductivity.2020-01-15
Rare earth ions (REIs) doped oxyfluoride glass-ceramic materials, with their low phonon energy and intensive upconversion luminescent properties, have garnered extraordinary attention in bio-imaging, photovoltaic devices, optical communications, t...2020-01-08
Ultra-high intense laser pulses have been applied in the field of laser-matter interaction, such as proton or electron acceleration in thin solid targets and electron generation in fast-ignition inertial confinement fusion. State-of-the-art high-p...2020-01-08
Joint time and frequency transfer in optical fiber has been widely discussed and there are several kinds of schemes. However, they all have such limitations as employing additional wavelength channels in metropolitan network and introducing electr...2019-12-24
Angular momentum is an intrinsic property of light, with spin angular momentum (SAM) of h (h is the Planck’s constant) per photon carried by circularly polarized (CP) light. It has been demonstrated that light beams with helical phase-fronts (opt...2019-12-16
