Finite-element simulations of optical cavities are presented, showing frequency splittings in the resonance spectrum. These can be directly compared to and understood by recent theory and experiments. They provide strong evidence for the no...
Tartrazine-enabled enhanced image depth penetration with quantitative oblique back-illumination microscopy [0.03%]

Jacob P Callaway et al.
In biological samples, optical imaging technologies are inherently limited by light scattering in thick tissues. Recently, water-soluble, strongly absorbing dye molecules, such as tartrazine, have demonstrated reversible in vivo optical tra...
Gaussian-modulated continuous-variable quantum key distribution over 60 km fiber using an integrated silicon photonic receiver [0.03%]

Xuesong Xu,Lu Fan,Yan Pan et al.
Xuesong Xu et al.
Fully integrated photonic continuous-variable quantum key distribution is a promising route toward compact and scalable secure optical links, yet the achievable transmission distance has been limited by the performance of integrated receive...
E2E-OCT: end-to-end joint learning model using optical coherence tomography images for vocal cord leukoplakia diagnosis [0.03%]
基于光学相干层析成像的声带黏膜白斑病变端到端联合诊断模型
Yu Ban,Yipeng Zhang,Xueying Li et al.
Yu Ban et al.
In our previous study, a home-built handheld OCT system was used to collect OCT images in vocal cord leukoplakia. First, 383 valid OCT images were collected from 12 patients with leukoplakia (including low-risk, high-risk, and malignant typ...
Holographic generation of panoramic 3D scenes by concave ellipsoidal mirror reflection [0.03%]

Yusuke Sando et al.
Conventional holographic three-dimensional (3D) displays have a limited ability to enlarge their field of view (FOV) and cannot reconstruct panoramic 3D scenes. This paper proposes a method to overcome this limitation by using a concave ell...
Dual-pilot phase recovery with pair-wise maximum-ratio combining for coherent PONs [0.03%]
基于成对最大比合并的双导频相位恢复算法用于相干PON系统
Chen Ding,Yutian Liu,Qiarong Xiao et al.
Chen Ding et al.
Non-orthogonal multiple access (NOMA) combined with digital subcarrier multiplexing (DSCM) enables dense and flexible coherent passive optical networks (PONs). However, NOMA signal superposition biases pilot-aided carrier-phase recovery (CP...
Mapping the whispering gallery modes of a CaF2 disk resonator with half-tapered fibers to estimate the fundamental mode volume [0.03%]
使用半倾斜光纤映射CaF2盘形谐振器的耳语画廊模式以估算基模体积
A S Bhadkamkar,T G Rottiger,P R Gupta et al.
A S Bhadkamkar et al.
Many applications that utilize whispering gallery mode resonators critically rely on the mode volume. In this work, we demonstrate a new, to the best of our knowledge, experiment to map the whispering gallery modes of a mm-sized disk resona...
Quantitative estimation of deep-subwavelength scale via dark-field scattering axial energy concentration decay profiles [0.03%]

Manzhuo Wang et al.
An optical switch scheme based on large fan-in/fan-out multimode interference (MMI) couplers is proposed to enable compact, low-loss N × N switching with channel uniformity. Specifically, two identical 8 × 8 MMI couplers are connected via...
