On the Cover: Rapid fabrication of microrings with complex cross section using annular vortex beams
The image on the cover for Chinese Optics Letters Volume 20, Issue 2, proposes a ring-shaped focus with controllable gaps by multiplexing the vortex beam and annular beam. The multiplexed beam has several advantages, such as the diameter and flow energy of the focal point can be individually controlled and are not affected by the zero-order beam, and the gap size and position are controllable.The image is based on original research by Chenchu Zhang et al. presented in their paper "Rapid fabrication of microrings with complex cross section using annular vortex beams", Chinese Optics Letters 20 (2), 023801 (2022).The image on the cover for Chinese Optics Letters Volume 20, Issue 2, proposes a ring-shaped focus with controllable gaps by multiplexing the vortex beam and annular beam.

On the Cover: Entanglement-based quantum key distribution with a blinking-free quantum dot operated at a temperature up to 20 K
The image on the cover for Advanced Photonics Volume 3 Issue 6 demonstrates blinking-free emission of highly entangled photon pairs from GaAs QDs embedded in a p-i-n diode. High fidelity entanglement persists at temperatures of at least 20 K, which is used to implement fiber-based QKD between two buildings with an average raw key rate of 55 bits / s and a qubit error rate of 8.4%. The image is based on original research presented in the report by Christian Schimpf, et al., “Entanglement-based quantum key distribution with a blinking-free quantum dot operated at a temperature up to 20 K,” Adv.
