Flat bands and quasi-bound states in the continuum in a photonic Moir? lattice

Ibrahim Nasidi et al.

Summary: This paper proposes the existence of flat bands and quasi-bound states in a moire lattice. Through controlling the inter-node coupling, the moire flat bands can be obtained. The moire lattice exhibits both singular and non-singular flat bands simultaneously. The Q-BIC in the moire lattice shows ultra-high quality factor, ultra-low mode volume, and very narrow linewidth, making it suitable for lasing and nanocavity applications.

Artificial neural networks assisting the design of a dual-mode photonic crystal nanobeam cavity for simultaneous sensing of the refractive index and temperature

Zixing Gou et al.

Summary: We propose a dual-mode photonic crystal nanobeam cavity for simultaneous sensing of refractive index and temperature. With the assistance of artificial neural networks, the sensitivities of the two modes are improved. By training the neural networks to predict the band structure and reverse design the geometric structure, a dual-mode nanobeam sensor with high quality factors and a small footprint is designed. The RI and T sensitivities for the air mode are 405 nm/RIU and 40 pm/K, while those for the dielectric mode are 531 nm/RIU and 27 pm/K.

Slow light bimodal interferometry in one-dimensional photonic crystal waveguides

Luis Torrijos-Moran et al.

Summary: Researchers have demonstrated slow light bimodal interferometric behavior in an integrated single-channel one-dimensional photonic crystal for the first time. This structure supports two electromagnetic modes with a large group velocity difference, resulting in over a 20-fold reduction in higher-order mode group velocity compared to other conventional interferometers. The proposed bimodal photonic crystal interferometer shows significant performance improvement in creating an ultra-compact optical modulator and a highly sensitive photonic sensor.

Summary: The ability of photonic crystal waveguides to confine and slow down light makes them ideal for enhancing the performance of various photonic devices, but integrating them in applications poses design challenges such as engineering mode dispersion and coupling devices. This study addresses these challenges through photonic inverse design, demonstrating a slow-light PCW optical phased array with a wide steering range.

Si photonic crystal slow-light waveguides optimized through informatics technology

Keisuke Hirotani et al.

Summary: Machine learning was used to model the photonic bands of SiO2-dadded Si lattice-shifted photonic crystal waveguides, leading to the discovery of a structure that can generate low-dispersion slow light with a group index of approximately 20 in the full C-band at telecom wavelengths. The transition structure between this waveguide and a Si-channel waveguide was designed using an evolutional optimization, resulting in a C-band average loss of 0.116 dB/transition. These results suggest the potential for further enhancing the versatility of slow light.
