Due to its large electric dipole moment, the Rydberg atom exhibits a strong response to weak electric fields, hence it is regarded as a highly promising atomic antenna. However, to enhance the reception sensitivity, split-ring resonators are needed normally, which will brings sensing blind spots. Thus it is not conducive to the application of full-coverage space communication. Here we propose that an atomic antenna with an asymmetric parallel-plate resonator, can not only enhance the received signal, but also eliminate sensing blind spots (pattern roundness can reach 7.8 dB while the split-ring resonator can be up to 39 dB). We analyze the influence of structural parameters on the field enhancement factor and directionality, and further discuss the limitation of the sensitivity by using thermal resistor noise theory.This work is expected to pave the way for the development of field-enhanced Rydberg atomic antennas that communicate without a blind spot.

“…It has gained significant attention across various fields such as sensing [1,2] and endoscopic imaging [3]. Traditional bulky optical components like gradient-refractive-index (GRIN) lenses [4,5], plane-concave lenses [6], and refractive ball lenses [7,8] have been mounted on the end face of the optical fiber to achieve corresponding functions in fiber optic imaging, sensing and light field modulation. There is no doubt that "lab-on-fiber" further expands the application scenarios of optical fibers.…”

Metasurfaces can arbitrarily manipulate the amplitude, phase, and polarization of optical fields on subwavelength scales. Due to their arbitrary manipulation and compact size, the metasurface can be well integrated with optical fibers. Herein, we demonstrate a polarization-dependent metasurface using birefringent meta-atoms, which can independently control X- and Y-polarization incident light. Each meta-atom allows for the division of phase into 16 steps ranging from 0 to 2π for both X- and Y-polarization, resulting in 256 nanopillars selected from the meta-atom library to satisfy the required phase. With the different effective refractive indices of the cuboid meta-atoms along the X- and Y-axis, we can achieve collimation of the X-polarization emitted beam from an optical fiber while deflecting orthogonally polarized light. As a result, the proposed metasurface collimates an X-polarized beam with a beam radius of 20 μm at z = 1 mm and 43.9 μm at z = 2 mm. Additionally, the metasurface can effectively deflect the Y-polarized beam to 36.01°, consistent with the results of the theoretical computation. The proposed metasurface exhibits a deflection efficiency of 55.6% for Y-polarized beams with a relative polarization efficiency of 82.2%, while the efficiency for the X-polarization is 71.4%. Our work is considered a promising application for optical communication, sensing, and quantum measurement.

“…[14][15][16][17] Confronting with these issues, multifunctional metasurfaces, which exhibit powerful electromagnetic (EM) manipulation capabilities with small configuration, low material loss, and easy fabrication, have attracted considerable attention and also been employed to design high-efficiency SSPP metacouplers in recent years. [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] For example, unidirectional SSPP metacouplers and polarization-controlled tunable metacouplers have been widely reported in different-frequency domains (e.g., microwave, terahertz, and optical). [12,[36][37][38][39][40][41][42] However, the inability of these SSPP metacouplers for wavefront manipulation restricts their further development and applications.…”

Circularly polarized (CP) spoof surface plasmon polariton (SSPP) functional metadevices, especially those with spin decoupling and hybrid modes, play an important role in modern photonics applications. However, currently available SSPP functional metadevices have the defect of restricted functionalities and single‐working modes for a given polarization, as it is a great challenge to simultaneously support SSPPs with hybrid modes and different wavefronts. Herein, a general strategy is proposed for designing CP SSPP functional metadevices with spin decoupling and hybrid modes based on transmissive spin‐decoupled metasurfaces and angle‐insensitive anisotropic SSPP eigenmode plates (EMPs). The metasurface can simultaneously and independently control the resonant and geometrical phases of the CP waves, and the SSPP EMP satisfies the hybrid‐mode (both transverse magnetic [TM] and transverse electric [TE] modes) momentum matching with high angular/momentum stability of the propagating SSPPs. For verification, a CP SSPP beam splitter is designed, fabricated, and experimentally demonstrated, which can convert incident right‐handed (R) and left‐handed (L) CP plane waves to CP hybrid‐mode SSPP deflected beams and decoupled beams, respectively. The work paves the way for the realization of CP SSPP multifunctional‐integration metadevices with hybrid modes and other functionalities, which can find extensive applications in different frequency domains.
