    Figures & Tables(5)
    (a) Schematic of the LCORR for PT/PA-effect observation. (b) Resonance-shift measurement. The transmission intensity of the quadrature-locked probe light is modulated by the PT/PA-induced resonance shift. (c) Experimental setup for optical detection of the PT/PA effect in an LCORR. PD, photodetector; EDFA, erbium-doped fiber amplifier.
    Transmission spectrum of the resonator over a 50 nm wavelength range. Inset: enlarged spectrum near 1530 nm.
    (Color online) Measured waveform of PA and PT signals detected by the LCORR. The green dash-dot curve plots the calculated thermal response based on the model depicted in Fig. 4(a). Inset: close-up of the PA signals.
    (Color online) (a) Axial symmetrical model for the calculation of the thermally induced response of the LCORR. (b) Calculated evolution of radial temperature profile. Inset: enlarged result over the silica wall.
    (a) PA waveform series extracted from Fig. 3. Inset: enlarged single PA waveform. (b) Frequency response.
