A novel scheme is introduced to achieve optical self‐tuning in ferroelectric lithium niobate (LN) metasurfaces equipped with a thin film of liquid crystals (LCs). The resonant optical field distributions inside the meta‐atoms can induce a photovoltaic (PV) field, which reorients the surrounding LCs.

The article explores the need for transparent conductive electrode in the context of nanocrystal based infrared photodetectors beyond traditional transparent conductive oxide and metallic grids. Use of such sensor for imaging where the diode is deposited on a read‐out integrated circuit raised the need for top transparent electrode.

Tunable‐Wavelength Broadband Liquid‐State Carbon‐Quantum‐Dot Lasers
This work provides a gain‐induced waveguide structure to achieve programmable mode spacing by coupling liquid‐state lasing of carbon quantum dots to a vertically placed aluminum mirror, enabling an unprecedented transition from random lasing to multimode lasing without cumbersome micromanufacturing, even single‐mode lasing at a wide range from 641 to ...

Improvement of Cu Ablation Efficiency Using GHz‐Burst Femtosecond Laser at 515 nm Wavelength
The green‐wavelength gigahertz (GHz)‐burst mode significantly improves the Cu ablation efficiency due to the interaction of subsequent intra‐pulses in a GHz‐burst with molten Cu. The superiority of the green‐wavelength GHz‐burst mode over the infrared‐wavelength one for a higher performance of Cu ablation at a smaller number of intra‐pulses is ...
