Highly Efficient Color Tuning of Lithium Niobate Nanostructures on Flexible Substrate Open
Nanostructures based on flexible material are essential for modulating reflected colors by actively changing the unit structure. However, current nanostructures face challenges in achieving active and efficient modulation across a broader …

Ultrahigh Quality Factor Photonic Nanojets Generated by Truncated Microtoroid Structures Open
A photonic nanojet (PNJ) is a highly confined light beam that focuses from the shadow side of microparticles. In this work, we propose a PNJ with ultrahigh quality factor formed by dielectric truncated microtoroid. The key properties of PN…
