An ultra-compact, ultra-wide-bandwidth in-phase/quadrature modulator on a silicon chip is demonstrated, enabling coherent transmission for symbol rates up to 180 Gbaud and a net bit rate surpassing 1 Tb s⁻¹ over an 80 km span, with modulation energy consumption as low as 10.4 fJ bit⁻¹, and promising enhanced performance and scalability for future networking infrastructures.

Multi-resonant Au/Si particles exhibit unique photoluminescence spectra, enabling creation of physical unclonable functions with sub-diffraction-limited critical sizes. These findings pave the way for advanced anti-counterfeiting and cryptography.

In this work, we introduce programmable memory elements embedded within III-V/Si light sources which facilitate non-volatile wavelength tuning for fast memory search and in-memory computing functions.

We present the demonstration of Raman spectroscopy using a SiN photonics chip spectrometer. This spectrometer will contribute significantly to wearable devices for non-invasive detection, forensic analysis, and space exploration.

An article in Nature presents an approach for the cost-effective and scalable integration of electrically pumped III–V-based lasers onto silicon wafers using a CMOS pilot prototyping line.

Non-reciprocal magneto-optics memory enables an integrated photonic platform that supports powerful matrix-vector multiplication computing and fast, efficient, fatigue-free programming capabilities.

Harnessing the large-scale integration and individual control of artificial atoms on silicon photonic circuits enables the realization of a rapidly programmable topological photonic chip that can be dynamically reconfigured to explore diverse topological phenomena.
