We report a Si3N4 microresonator which simultaneously satisfies single-mode operation, high Q-factor and anomalous dispersion. With controlled high-speed pump-wavelength scanning, we successfully observe a smooth phase-locked Kerr frequency comb transition based on dissipative solitons.
Absorptive optical nonlinearity is demonstrated in silicon nitride rings with ∼244,000 intrinsic quality factors. Thermal induced optical nonlinearity leads to stochastic bistable switching in the absence of free carrier dispersion, towards CMOS-compatible photonic integrated circuits.
Ultra-high-Q nanocavity resonance tuning by laser-assisted thermal oxidation of silicon is demonstrated by using a 532 nm continuous wave laser. The resonance is blue-shifted by >2nm. The quality factor remains >200,000.
In this paper, we present for the first time the direct observation of pulse compression in slow-light photonic crystals. A compression of a 3 ps pulse down to 600 fs was observed with an input power as low as 17 pJ.
We demonstrate integrated optical ring resonators as time-resolved sensors with 3.2×10−5 refractive index unit sensitivity embedded in microfluidic channels. Furthermore, we report the chip-scale detection of segmented flow with different liquid-film thicknesses and capillary numbers.
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.
