Integrated chip-scale electrodes allow isolated control of resonances and phases in optical multi-cavity system. By varying the round trip length, destructive and constructive intra-cavity interferences are observed, representing all-optical analogue to electromagnetically-induced-transparency and superradiance on-chip.
We demonstrate tunable temporal delays in coherently-coupled multi-cavity photonic crystals, in analogue to EIT. We report deterministic control of the group delay, up to 7' the single cavity lifetime, in our CMOS-fabricated chip.
We present the integrated chip-scale tuning of multiple photonic crystal cavities. The optimized implementation allows for large tuning (20K/mW), with deterministic resonance control towards all-optical analogue to electromagnetically-induced-transparency on-chip.
Photonic crystal filaments were demonstrated with noncollinear filaments interaction, resulting in elongated filaments and third harmonic generation of more than two orders enhancement as compared with that from a single filament.
We present experimental analysis of weak coupling for monolayer lead sulfide quantum dots coupled to silicon photonic crystal cavities between 4 K and room temperature, as well as power-saturation measurements of dots at 4 K.
We describe a scalable nanocavity array, with single quantum dots, for universal single-operation N-qubit quantum gate. A single two-level system controls the lineshapes, departing from optical-analog of electromagnetically-induced-transparency, with high fidelity and low photon loss.
By virtue of a silicon high-Q photonic crystal nanocavity, we propose and examine theoretically interactions between a stationary electron spin qubit of a semiconductor nanocrystal and a flying photon qubit.
