Abstract Terahertz modulators play a critical role in high-speed wireless communication, non-destructive imaging, and so on, which have attracted large amount of research interest. Nevertheless, all-optical terahertz modulation, an ultrafast dynamical control approach, remains to be limited terms encoding multifunction. Here we experimentally demonstrated optical-programmed switching realized by combining optical metasurfaces with the metasurface, resulting 2-bit dual-channel encoding. The...
Exceptional points (EPs), known as non-Hermitian degeneracies featuring missing eigenspace dimensions, have led to a variety of intriguing wave phenomena in various physical platforms. Chiral EPs collapsing two orthogonal eigenstates can lead unique effects and applications, such loss-induced transparency, EP-enhanced sensing, chirality-reversal electronics, etc. However, previous experiments, chiral were typically induced fixed structures with inherent active gains or nearby nanotips, which...

In photonics, achieving high-quality (Q) resonance is crucial for high-sensitivity devices used in applications, such as switching, sensing, and lasing. However, high-Q resonances are highly susceptible to internal losses of plasmonic devices, impeding their integration into broader systems across terahertz visible light bands. Here, we overcome this challenge by proposing a low-Q metasurface ultrasensitive (THz) switching sensing. Theoretically, reveal an approach constructing resonator...

Understanding hypoxia's role tumorigenesis is highly essential for developing effective therapeutics, which necessitates reliable tools to specifically distinguish tumor cells (or tissues) and correlate their dynamics with the status disease complex living settings precise theranostics. So far, disparate hypoxia‐responsive probe molecules prodrugs were designed via...
The crosstalk between tumors and their local microenvironment has been well studied, whereas the effect of on distant tissues remains understudied. Studying how affect other is important for understanding systemic improving overall health cancer patients. In this study, we focused changes in intestine during liver tumor progression, using a previously established model through inducible expression oncogene xmrk zebrafish. Progressive disruption intestinal structure was found fish, displaying...
Abstract Laser speckle imaging (LSI) as a label-free flow mapping technique has numerous potential clinical applications and plays an increasingly important role in translational medicine. Conventional LSI, however, is limited to qualitative change assessment two-dimensional topographic imaging. Here we report light-sheet laser (LSH-LSI) platform.

The GNSS-based bistatic SAR (GNSS-BSAR) system has emerged as a hotspot due to its low power consumption, nice concealment, and worldwide reach. However, the weak landing density of GNSS signal often necessitates prolonged integration achieve an adequate signal-to-noise ratio (SNR). In this case, effects receiver’s time-frequency errors atmospheric disturbances are significant cannot be ignored. Therefore, we propose ionospheric scintillation compensation-based imaging scheme for...

The mathematical theory of braids, influential across scientific disciplines, has emerged as a compelling strategy for light manipulation. Existing approaches to creating braids in photonics, whether momentum-space bandstructures or real-space fields, often face limitations associated with static nature devices and lack tunability. Here, we experimentally demonstrate ultrafast control eigen-spectrum Jones matrices within mere picoseconds, reconfigurable non-Hermitian metasurfaces. the...
