The application of electric fields induces changes in the symmetry of crystals, which can be observed spectroscopically as variations in the even harmonic generation. In this study, we report the ultrafast modulation of GaAs crystal symmetry using strong terahertz field. The modulation is recorded b...

Vegetation water-use efficiency (WUE), which represents the trade-off between carbon assimilation and water consumption, is a key indicator of ecosystem adaptation to environmental change. While previous studies have addressed the climatic controls on WUE in alpine ecosystems, the quantitative respo...

K9 glass is prone to developing color center defects under gamma irradiation, which exhibit strong absorption at specific laser wavelengths. However, most of these color centers exhibit an annealing phenomenon in natural environmental conditions, wherein their absorptive characteristics gradually di...

In this paper, we propose and fabricated a novel scheme of SOI-based 1 &#x00D7; 3 coupler with variable splitting ratio. The coupler consists of two cascaded MMI with different sizes, and a wide range of splitting ratios from 1:0.1:1 to 1:18:1 can be achieved by modifying the size of the first-s...
