We experimentally investigate the unidirectional coupling between two semiconductor frequency combs generated by two passively mode-locked quantum dot lasers. We show that synchronization of the combs in terms of repetition rate and phase locking is possible for a wide range of detuning between the combs. Repetition rate locking of the combs leading to reduced phase noise operation for the slave comb

Analytical fields of ultrashort radially polarized laser beams with spatial chirp J. Opt. Soc. Amer. B (IF 1.9) Pub Date : 2024-02-07 Spencer W. Jolly and Miguel A. Porras
We find the analytical electromagnetic fields, both paraxial and with non-paraxial corrections, of an ultrashort radially polarized pulse-beam that has spatial chirp. This represents a powerful description of light that has a combination of both vector polarization and space-time structure, and it results in a novel evolution of the fields. The non-paraxial corrections allow for the application of

Enhancement sensing of biomarkers by acoustic graphene plasmonic mode J. Opt. Soc. Amer. B (IF 1.9) Pub Date : 2024-02-05 Hang Piao, Qing Chen, Xiangyu Li, Jingzhi Wu, Yanhong Wang, and Mengwei Li
The sensitivity and accuracy of molecular detection using THz technology are limited due to the weak interaction between THz waves and biomolecules. An acoustic graphene plasmons (AGP) resonator could have ultra-compressed light fields and provide strong light-matter interactions at the microscopic level. In the paper, the AGP construction for bio-molecules sensing with high sensitivity is proposed

Validation and characterization of algorithms and software for photonics inverse design J. Opt. Soc. Amer. B (IF 1.9) Pub Date : 2024-01-31 Mo Chen, Rasmus E. Christiansen, Jonathan A. Fan, Göktuğ Işiklar, Jiaqi Jiang, Steven G. Johnson, Wenchao Ma, Owen D. Miller, Ardavan Oskooi, Martin F. Schubert, Fengwen Wang, Ian A. D. Williamson, Wenjin Xue, and You Zhou
In this work, we present a reproducible suite of test problems for large-scale optimization (“inverse design” and “topology optimization”) in photonics, where the prevalence of irregular, non-intuitive geometries can otherwise make it challenging to be confident that new algorithms and software are functioning as claimed. We include test problems that exercise a wide array of physical and mathematical

Linear electro-optical analysis model of a lithium niobate thin film modulator with arbitrary crystal axis orientation J. Opt. Soc. Amer. B (IF 1.9) Pub Date : 2024-01-29 Ye Li, Lihong Hong, Baoqin Chen, and Zhi-Yuan Li
We propose an improved model for the electro-optic (EO) properties of a thin film lithium niobate (TFLN) Mach-Zehnder (MZ) electro-optic modulator (EOM) with arbitrary crystal axis orientation. We develop an analytical theory based on second-order nonlinear optics to describe the linear EO effect and establish an approximate calculation method with the aid of coupling theory and perturbation theory

Suppression of wave-particle duality in multiple slit experiments J. Opt. Soc. Amer. B (IF 1.9) Pub Date : 2024-02-01 E. Pavel
In this paper, we investigated a five-slit diffraction experiment with multiple photons and a quantum confinement effect (QCE) image sensor. Two types of diffracted photons were identified: (i) Type I with particle behavior and (ii) Type II with wave behavior. Type I and Type II diffracted photons have been characterized. The research showed new aspects of the breakdown of the diffraction limit by
