Actuation bandwidth extension of an integrated piezo-optomechanical nanophotonic device

Tobias Kippenberg, Junqiu Liu, Wenle Weng, Anat Siddharth

We demonstrate a novel technique of contour-mode suppression of an integrated MEMS-photonic chip up to the first HBAR mode at 17 MHz. The flattened actuation response is critical to the development of compact LiDAR engine or low-noise frequency-agile laser ...

X-Band Aom On Chip

Tobias Kippenberg, Junqiu Liu, Anat Siddharth

Silicon Nitride integrated photonic circuits have drawn much attention owing to its ultra-low loss and large Kerr nonlinearity. However, the lack of Pockels effect makes it difficult to be modulated clectro-optically, which posts a major challenge for the ...

Wafer-scale fabrication of ultralow-loss silicon nitride nonlinear photonic circuits

Rui Ning Wang, Tobias Kippenberg, Maxim Karpov, Junqiu Liu, Miles Henry Anderson, Arslan Sajid Raja, Nils Johan Engelsen, Wenle Weng, Anton Lukashchuk, Guanhao Huang, Jijun He, Mikhail Churaev, Anat Siddharth, Alexey Tikan

Recent advances in silicon nitride integrated photonics have achieved ultralow optical losses. Transferring this technology to standard commercial foundries, and merging it with silicon photonics via heterogeneous integration, will seed novel laser and qua ...

A Nitride Ring Isolator

Tobias Kippenberg, Junqiu Liu, Anat Siddharth

A silicon nitride optical ring isolator is realized by spatiotemporal modulation using bulk acoustic wave stress-optical transducers. By driving three actuators with fixed relative phases, over 17 dB isolation is achieved. (C) 2020 The Author(s) ...
