(a) Transmission spectrum (fiber A). Inset: Lorentzian fit (dashed line) to determine Q for resonance, at low () power. (b) Transmission spectrum as a function of coupled input power as labeled in legend.
Experimental setup for all-optical modulation.
Modulated (a) pump and (b) probe signals at 25 Hz. (c) Modulated probe at 21 kHz.
(a) Measured amplitude response of the probe beam as a function of the modulation frequency of the pump. The dashed lines show a –3 dB corner frequency of 21 kHz. (b) Absorbed power versus cavity energy. Results obtained for fiber (A).
