We demonstrate free-space coupling to microtoroids using one objective to excite and collect scattered resonant light. We achieve Q-factors > 10⁸ and perform sensing with an SNR > 26 dB.

We introduce an innovative quartz-enhanced multiheterodyne resonant photoacoustic spectroscopy technique that utilizes a quartz tuning fork to achieve resonant detection of a dual comb based on the photoacoustic effect.

We explore an open trajectory linking two infinite points having the same asymptotic eigenmodes, demonstrating that this platform enables high-efficiency chiral transmission, with each eigenmode localized in a single waveguide.

We propose a general theory concerning Bloch oscillations in photonic Floquet lattices and report the first visual observation of the Bloch-like oscillations, which are termed the “photonic Floquet–Bloch oscillations.”

We demonstrate a novel superconducting LWIR sensor integrating the function of infrared sensitivity, memory and reconfigurable logic computing.

Non-Hermitian skin states, an exotic form of quantum states condensed at the boundary of certain dissipative systems, are disclosed in incoherent models of quantum walks in synthetic photonic matter.

The stereoscopic photoacoustic microscopy is proposed to achieve wide-field intravital imaging of the lymphatic system in mice, facilitating three-dimensional high-resolution visualization of meningeal lymphatic vessels on the meninges.

This work studies luminescence from monocrystalline gold flakes down to 13 nm thick. It reveals this signal is photoluminescence, with signals reproduced by density functional theory, resolving a decade-old puzzle.
