Abstract

Linear and non-linear thermo-optical dynamical regimes were investigated in a photonic crystal cavity. First, we have measured the thermal relaxation time in an InP-based nano-cavity with quantum dots in the presence of optical pumping. The experimental method presented here allows one to obtain the dynamics of temperature in a nanocavity. It is based on reflectivity measurements of a cw probe beam coupled through an adiabatically tapered fiber. Characteristic times of 1.0±0.2 µs and 0.9±0.2 µs for the heating and the cooling processes were obtained. Finally, thermal dynamics were also investigated in a thermo-optical bistable regime. Switch-on/off times of 2 µs and 4 µs respectively were measured, which could be explained in terms of a simple non-linear dynamical representation.

  23. Convection within the air gap can be neglected since the Rayleigh number for an air gap of thickness ? between two rigid walls, for a few degrees of temperature increment, is Ra?=g ?T ?3/a?T~10-10, whereas the onset for convection is Ra?~2 103.

  26. The thermal relaxation time for a PhC membrane on oxide can be easily calculated under the hypothesis of 1D vertical heat flow through the oxide layer to the substrate. For instance, for a 250 nm-thick Si membrane (?Si=1.5 W/cm K, ?Si=0.9 cm2/s) in contact with a 1 µm-thick SiO2 layer (?SiO2=0.013 W/cm K, ?SiO2=0.006 cm2/s), a numerical simulation of the 1D heat equation gives tth=950 ns.

  28. We use the estimated ?th from the experimental results, ?th~110 ns (see Section 6.1). This is an approximation since ?th depends on the geometry of the hot spot which, in the resonant case, is given by the cavity volume, different from the pumped region given by the surface illumination.
