Simultaneous Kerr comb formation and second-harmonic generation with on-chip microresonators can greatly facilitate comb self-referencing for optical clocks and frequency metrology. Moreover, the ...

Boosting Second Harmonic Generation with TMDs Monolayer Via Dual Bound States in The Continuum In A Photonic Grating Slab A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022. ...

Conversely, by performing an inverse operation of the third-order tensor representation of the second harmonic wave, the original input information can be retrieved through a decryption process.

The second diagram below the top one shows the second harmonic with a pattern of one full wavelength (including a node in the middle) and a frequency of 2f. This pattern continues with the 3rd and 4th ...
