Popis: |
We demonstrate that frequency-converting devices of high quality can be realised with glass poling. The devices, made with silica-on-silicon technology, are poled with periodic, embedded electrodes, and used for second-harmonic generation. We obtain precise control of the quasi phase-matching wavelength and bandwidth, and a normalised conversion efficiency of 1.4 × 10-3 %/W/cm2 which, to our knowledge, is the highest obtained so far with periodic glass poling. |
