“…For this case, the measured peak modulation depth is I 0 /I min = 2.0. Here the modulation occurs over the entire mode spectrum, and clearly differs from the static modulation of the SE rate using PhC cavities 22 and the dynamic modulation, which may, in principle, be obtained by changing the emittercavity detuning with ultrafast control of the cavity wavelength 11,12,23 or by Stark tuning of the exciton energy 8 . Indeed, our method directly changes the SE rate by controlling the interaction term g and loss rate κ.…”

Solid-state cavity quantum electrodynamics systems will form scalable nodes of future quantum networks, allowing the storage, processing and retrieval of quantum bits, where a real-time control of the radiative interaction in the cavity is required to achieve high efficiency. We demonstrate here the dynamic molding of the vacuum field in a coupled-cavity system to achieve the ultrafast nonlocal modulation of spontaneous emission of quantum dots in photonic crystal cavities, on a timescale of ~200 ps, much faster than their natural radiative lifetimes. This opens the way to the ultrafast control of semiconductor-based cavity quantum electrodynamics systems for application in quantum interfaces and to a new class of ultrafast lasers based on nano-photonic cavities.

“…We observed direct, ultrafast 20 GHz nonlinear optical tuning of photonic crystal PC cavities containing quantum dots QDs. 15 Switching via free-carrier generation is limited by the lifetime of free carriers and depends strongly on the material system and geometry of the device. In our case, the large surface area and small mode volume of the PC reduce the lifetime of free carriers in GaAs.…”

We have recently demonstrated a number of functional photonic crystals devices and circuits, including an ultrafast, roomtemperature, low threshold, nanocavity laser with the direct modulation speed approaching 1 THz, an all-optical switch controlled with 60 fJ pulses and with the speed exceeding 200Hz, and a local, reversible tuning of individual quantum dots on a photonic crystal chip by up to 1.8nm, which was then used to tune single quantum dots into strong coupling with a photonic crystal cavity and to achieve a giant optical nonlinearity.

“…These examples indicate that active tuning of PhC devices is indispensible for applicable functionalities. The refractive index can be tuned with optical [5], mechanical [6] and electrical methods [7]. Another method is infilling the air hole(s) of a cavity in a PhC with a liquid crystal.…”

Thermal tuning of a silicon photonic crystal cavity infilled with an elastomer

et al. 2011

Thermal tuning of the transmission of an elastomer infilled photonic crystal cavity is studied. An elastomer has a thermal expansion-induced negative thermo-optic coefficient that leads to a strong decrease of the refractive index upon heating. This property makes elastomer highly suitable for thermal tuning of the transmission of a cavity, which is demonstrated by global infilling of a hole-type silicon photonic crystal slab and global thermal tuning. In the temperature range 20-60 0 C the cavity peak shows a pronounced elastomer-induced blue shift of 2.7 nm, which amply overcompensates the red shift arising from the thermo-optic property of the silicon. These results qualify the elastomer for tuning by local optical heating.
