Probing material absorption and optical nonlinearity of integrated photonic materials

Tobias Kippenberg, Junqiu Liu, Guanhao Huang

Optical microresonators with high quality (Q) factors are essential to a wide range of integrated photonic devices. Steady efforts have been directed towards increasing microresonator Q factors across a variety of platforms. With success in reducing microf ...

Planted XY model: Thermodynamics and inference

Siyu Chen, Guanhao Huang, Giovanni Piccioli, Lenka Zdeborová

In this paper we study a fully connected planted spin glass named the planted XY model. Motivation for studying this system comes both from the spin glass field and the one of statistical inference where it models the angular synchronization problem. We de ...

Probing the Limits of Optical Loss in Ion-Sliced Thin-film Lithium Niobate

Tobias Kippenberg, Di Zhu, Junqiu Liu, Guanhao Huang, Mikhail Churaev, Zelin Tan

We measured the absorption-limited loss at telecommunication wavelengths for thin-film lithium niobate micro-ring resonators using Kerr-calibrated linear response technique. We find the average absorption loss-rate kappa(abs)/2 pi to be 3.65 +/- 0.70 MHz, ...
