Three-axis isotropic-sensitivity He4 magnetometer with alignment-based longitudinal parametric resonance

Physical Review A 2022年第6期106卷 063102-063102页

For measurements in near-zero magnetic fields, vector atomic magnetometers are promising alternatives to scalar versions, but generally suffer from inconsistent performance over three axes. We present a single-beam vector magnetometer with three-axis isotropic sensitivity based on He4 atomic alignment. Longitudinal parametric resonance with atoms pumped by linearly polarized light is proposed for the z-axis measurement, while the Hanle effect in transverse geometry is used for x- and y-axis measurements. The evolution of atomic alignment multipole components and expressions of the three-axis magnetic responses are analyzed in detail. We describe the experimental operation of the proposed magnetometer with a magnetic-field noise floor of 150fT/Hz1/2 for the three axes, which is attractive for biomagnetism requiring vector characterization and source reconstruction.

A novel multi-parameter sensor has been proposed based on the W-type leaky fibre grating, after the systematic investigation of its characteristics in response to the variation of temperature, surrounding refractive index and bend. The resonant wavelength for different mode in the reflection spectra has the same temperature sensitivity of ~9.13 pm/oC, but the reflection intensity has no dependence upon the temperature change. The resonant wavelength of different mode linearly varies a little with the refractive index change, however, its reflection intensity follows the negative exponential decay with refractive index increasing, where for the higher modes the sensitivity is higher. The resonant wavelength for each mode almost linearly responds to the displacement, giving out a displacement sensitivity of 99.94 pm/mm. However, the reflection response to the displacement varies a lot. Based on these results, simple and compact multi-parameter fibre sensors are proposed based on W fibre grating. © 2023 SPIE.

We investigate the integration of quantum key distribution (QKD) into classical optical communication links based on a field-deployed uncoupled-core four-core fiber. We experimentally characterize inter-core spontaneous Raman scattering (IC-SpRS) and evaluate the impact of IC-SpRS and dark counts on QKD performance as the classical traffic load is varied when three cores are used for classical WDM transmission and one for QKD. © 2024 IEEE.

Miniaturized spectrometer enabled by end-to-end deep learning on large-scale radiative cavity array

arXiv 2024年

作者： Zhou, Xinyi Zhang, Cheng Zhang, Xiaoyu Zuo, Yi Zhang, Zixuan Wang, Feifan Chen, Zihao Li, Hongbin Peng, Chao State Key Laboratory of Advanced Optical Communication Systems and Networks School of Electronics & Frontiers Science Center for Nano-optoelectronics Peking University Beijing100871 China Peng Cheng Laboratory Shenzhen518055 China

Miniaturized (mini-) spectrometers are highly desirable tools for chemical, biological, and medical diagnostics because of their potential for portable and in situ spectral detection. In this work, we propose and demonstrate a mini-spectrometer that combines a large-scale radiative cavity array with end-to-end deep learning networks. Specifically, we utilize high-Q bound states in continuum cavities with distinct radiation characteristics as the fundamental units to achieve parallel spectral detection. We realize a 36 × 30 cavity array that spans a wide spectral range from 1525 to 1605 nm with quality factors above 104. We further train a deep network with 8000 outputs to directly map arbitrary spectra to array responses excited by the out-of-plane incident. Experimental results demonstrate that the proposed mini-spectrometer can resolve unknown spectra with a resolution of 0.048 nm in a bandwidth of 80 nm and fidelity exceeding 95%, thus offering a promising method for compact, high resolution, and broadband spectroscopy. © 2024, CC BY.

SummaryWe report a frequency shifting scheme for on-chip optical frequency transfer with low external circuit requirements. Serrodyne modulation method is used to achieve frequency shifting with high carrier and sideband suppression ratios for optical carriers, and the method is also suitable for a wide range of integrated platforms. We first demonstrate the feasibility of the scheme using a commercial phase modulator, which is able to produce a frequency shift of over 1 MHz, a carrier suppression ratio of over 50 dB, a sideband suppression ratio of over 37 dB and a conversion loss of about 0.08 dB. We also design a phase modulator on thin film lithium niobate platform with a low half wave voltage about 2.18 V, which greatly reduces the requirements of the external circuit voltage for frequency shifting, and can achieve a frequency shift above 1 GHz. Our proposed scheme verifies the feasibility of on-chip frequency shifting with low loss and high suppression ratio, and paves the way for the integration of optical frequency transfer systems.
