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 study introduces a reconfigurable hybrid metasurface platform by incorporating the phase-change material Ge2Sb2Te5 (GST) into metal-dielectric meta-atoms for active and nonvolatile tuning of properties of light. The reduced-dimension meta-atom can selectively control the hybrid plasmonic-photonic resonances of the metasurface via the dynamic change of optical constants of GST, demonstrating promising applications in high-contrast optical switching and efficient beam deflection. Findings suggest dynamic hybrid metasurfaces as compelling candidates for next-generation reprogrammable meta-optics.

Summary: Researchers have designed and experimentally demonstrated an approach using doped III-V semiconductors to simultaneously control the spectral peak, bandwidth, and directionality of infrared emissivity. InAs-based gradient epsilon-near-zero (ENZ) photonic structures exhibit broadband directional emission with different spectral bandwidths and ranges depending on doping concentration profile and thickness. This approach provides a versatile photonic platform for dynamically controlling broadband spectral and directional emissivity in applications such as heat transfer and infrared sensing.

Summary: This study investigates the impact of interface roughness on a layered photonic crystal gas sensor based on Tamm resonance in the terahertz range. The performance of the sensor is observed for different thicknesses of the rough layer between adjacent layers. The results show that an increase in the rough layer between adjacent porous and cavity layers leads to a decrease in sensitivity but enhances the quality factor and figure of merit of the proposed structure. However, changing the thickness of the rough layer between the metallic and the last cavity layer does not affect the performance.

Summary: A broad range of imaging and sensing technologies in the infrared require large field-of-view operation. Traditional refractive systems often employ multiple elements to compensate for aberrations, leading to excess size, weight, and cost. Meta-optics, which are significantly thinner and lighter than traditional refractive lenses, can dramatically reduce the size, weight, and cost of these imaging systems. In this paper, an all-silicon meta-optic with an entrance aperture and lens focal length of 1 cm is used to demonstrate 80 degrees FoV thermal imaging in the long-wavelength infrared regime (8-12 μm).

Summary: Photonic integrated circuits (PICs) can greatly enhance the capabilities of optical information science and engineering. We propose using wide-bandgap non-volatile phase-change materials (PCMs) to create rewriteable PICs. A nanosecond pulsed laser can be used to write a PCM-based PIC without removing any material. The entire circuit can be erased by heating and a new circuit can be rewritten. Our proposed platform enables low-cost manufacturing and has significant implications for rapid prototyping of PICs, design validation, and photonic education.

Summary: Ultrathin flat meta-optics have shown promise for holography, but most reported holograms only modulate phase and neglect amplitude. Complex phase modulation typically requires polarization-sensitive meta atoms or complex scatterers. This study demonstrates polarization-independent holography with both amplitude and phase modulation using dielectric meta-optics. The researchers also show that meta-optical holography can be achieved using partially incoherent light from an LED, reducing alignment complexity.

Summary: Tunablenanophotonic resonators are crucial for material-integrated photonic systems and solid-state cavity quantumelectrodynamic experiments. Matching the cavity resonance with the material optical transition is important for enhancing light-matter interaction, which leads to various phenomena with implications in quantum optics and optoelectronics. However, precise control of the resonant wavelength of nanofabricated optical cavities is challenging, requiring postfabrication dynamical tuning, especially in cryogenic environments. In this study, we achieved large in situ strain tuning of an integrated monolayer WSe2-galliumphosphide cavity device. We successfully tuned an on-substrate cavity with a quality (Q)-factor of approximately 3500 at around 780nm by approximately 5nm without any degradation of the Q-factor at cryogenic temperature. The tunable cavity modes were observed as cavity-enhanced monolayer exciton photoluminescence.
