Summary: Photonic time-crystals are spatially homogeneous media that exhibit periodic variations in their electromagnetic susceptibility, leading to temporal reflections and refractions of propagating waves. Free electrons in these crystals spontaneously emit radiation, with a significantly amplified emission process when associated with momentum-gap modes. Quantum interference between spontaneous emission and electron emission into the band modes suppresses the interdependent emission. Therefore, the study of free-electron physics in photonic time-crystals offers a platform to explore various exciting phenomena.

Summary: This article demonstrates unidirectional bulk modes and robust edge modes in triangular photonic crystals. By changing the phase vortex of an input chiral source, dynamic unidirectional propagation of bulk modes at different valleys is observed. Unidirectional edge modes are also shown on the domain wall between two distinct triangular photonic crystals. In addition, robust edge modes around sharp corners are experimentally confirmed. This work paves the way for the realization of dynamic unidirectional photonic transport and robust valley transport in photonic crystals.

Summary: This paper presents a novel design of high Q-factor silicon nitride (SiN) 1D photonic crystal (PhC) cavities side-coupled to curved waveguides, which can operate with both silica and air cladding. The etched 1D PhC cavity sidewalls angle is engineered to achieve high Q-factors over a wide range of upper cladding compositions, resulting in the highest calculated Q-factor for non-suspended asymmetric SiN PhC structures. The SiN PhC cavities are demonstrated to be used in hybrid external cavity laser configuration, enabling mode-hop free single mode laser operation with high power output and side-mode suppression ratios. Moreover, these devices are applied as compact and energy efficient optical sensors, exhibiting high sensitivity to refractive index changes in the surrounding medium.

Summary: This paper presents a solution for implementing a sensor and an interrogator based on a silicon-on-insulator (SOI) integrated photonics platform, which achieves high-precision and high-speed frequency interrogation of the sensor. The results show that frequency interrogation can increase the intrinsic limit of detection (LoD) by five orders. This proposed solution opens up the possibility for fully integrated implementation of a photonic laboratory-on-a-chip unit.

Summary: In this study, an effective field theory was developed using differential geometry to study light propagation in distorted photonic crystals. The geodesic equation derived based on the principle of least action demonstrated that lattice-position distortion can curve the trajectory, providing multiple exact solutions for simple distortion conditions. These solutions explicitly showed that light bending only occurs through lattice distortion, consistent with finite-difference time-domain simulation results.

Summary: This paper introduces neuromorphic photonic processors based on resonator weight banks, which are emerging candidate technology for enabling modern artificial intelligence in high speed analog systems. These purpose-built analog devices leverage the physics of resonator devices to implement vector multiplications, offering efficiency, latency, and throughput advantages over equivalent electronic circuits. However, the challenges of compensation for fabrication variations and environmental disturbances need to be addressed through automated design and control methodologies for practical deployment.

Summary: Weyl points are point degeneracies in the momentum space of 3D periodic materials, associated with a quantized topological charge. This study experimentally observed the splitting of a quadratic Weyl point into two linear Weyl points in a 3D micro-printed photonic crystal. The theoretical analysis showed that this splitting occurs along high-symmetry directions in the Brillouin zone, which is important for the development of robust topological devices in the near-infrared.
