Cryptochromes (crys) are photolyase-like blue-light receptors first discovered in Arabidopsis thaliana and later identified all major evolutionary lineages. Crys involved not only blue light responses but also temperature responses; however, whether how cry protein stability is regulated by remains unknown. Here, we show that cry2 abundance modulated ambient degraded under low via the 26S proteasome. Consistent with this, shows high levels of ubiquitination temperatures. Interestingly,...
Integrated photonic devices play a key role in modern optical communications, of which resonators are important fundamental structures. This work proposes and experimentally demonstrates compact integrated based on traveling wave-like Fabry-Perot (TW-like FP) resonator(s) coupled with waveguides. Add-drop filters single TW-like FP resonator have been realized high drop efficiency the same output direction for through ports. Particularly, their transmission response can be either symmetric...
A reflowing photoresist and oxidation smoothing process is used to fabricate ultra-high-Q silicon microring resonators based on multimode rib waveguides. Over a wide range of wavelengths near 1550 nm, the average Q-factor ring with 1.2-μm-wide waveguides reaches up 1.17 × 106, waveguide loss approximately 0.28 dB/cm. For resonator 1.5-μm-wide waveguides, 1.20 0.27 Moreover, we theoretically experimentally show that reduction in significantly improves conversion efficiency four-wave mixing....

Optical switch is an essential component in integrated photonic circuits. A mode-conversion nanobeam cavity (MCNC) coupled with two waveguides has been employed to realize ultra-compact and low-loss 2 × thermo-optic switches silicon-on-insulator. This system can exhibit either Fano or Lorentzian lineshape transmission spectra, dependent on the coupling structure. It a low dropping loss, outputs are same direction, owing unidirectional between resonant mode bus waveguides. Here, we have...

We present a compact and efficient spot size converter (SSC) design method based on metasurfaces, which is suitable for beam transformation between single mode waveguide any wide multi-mode in theory. Two kinds of SSCs connecting 100 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\mu m$</tex> or 12 with 0.5 have been fabricated. Experiments show that the insertion losses are 0.81 dB 1.00 at 1550nm, respectively. For waveguide, both lower than...
