We perform resonant spectroscopy of erbium implanted into nanophotonic silicon waveguides, finding 1 GHz inhomogeneous broadening and homogeneous linewidths below 0.1 GHz. Our study thus introduces a promising materials platform for on-chip quantum information processing.

Spiking neural networks (SNN) provide a new computational paradigm capable of highly parallelized, real-time processing. Photonic devices are ideal for the design high-bandwidth, parallel architectures matching SNN paradigm. Furthermore, co-integration CMOS and photonic elements combineslow-loss with analog electronics greater flexibility nonlinear elements. We designed simulated an optoelectro...

Chiral nanostructures can enhance the weak inherent chiral effects of biomolecules and highlight important roles in detection.

Complex systems are a proving ground for fundamental interactions between components and their collective emergent phenomena. Through intricate design, integrated photonics offers intriguing nonlinear that create new patterns of light. In particular, the canonical Kerr-nonlinear resonator becomes unstable with sufficiently intense traveling-wave excitation, yielding instead Turing pattern compo...
