Brillouin gain enhancement in silica optical nanofibers
Résumé
We provide a new pump-probe method to accurately measure the Brillouin gain in the radio-frequency domain and we use it to measure the backward gain in silica optical nanofibers for the first time. A stimulated gain as high as g_B=11.3 /m/W for the L02 acoustic mode at 8.6 GHz was achieved, which is 50 times larger than a standard fiber. We also report a high Brillouin gain of up to 5 /m/W using surface acoustic waves below 6 GHz.
