Summary: A novel composite waveguide based on hybrid substrate integrated waveguide and spoof surface plasmon polariton (SIW-SSPP) is proposed in this paper. By utilizing different feeding methods, the odd mode and even mode of SSPP are excited simultaneously and operate at the same frequency band, achieving co-frequency mode multiplexing for the proposed odd-even mode composite waveguide (OEMCW). Experimental results demonstrate that the proposed waveguide can operate in the range of 10.3 GHz to 18 GHz with significant isolation between the modes.

Summary: An ultra-compact spoof surface plasmon polariton transmission line (UCSSPP TL) based on a meander line is proposed, achieving nearly the same transmission performance as conventional SSPP TL with a significant reduction in linewidth. The coupling effect between UCSSPP TLs in different line arrangements is studied, showing excellent crosstalk suppression in back-to-back arrangements and strong coupling in face-to-back or face-to-face arrangements. The signal integrity of back-to-back UCSSPP TLs is analyzed and demonstrated to be greatly improved compared to microstrip TLs. Additionally, an ultra-miniaturized SSPP coupler is designed using face-to-face UCSSPP TLs, achieving a size reduction of over 75% compared to conventional microstrip couplers.

Summary: Two filtering baluns exploiting a combination of spoof surface plasmon polariton (SSPP) and substrate integrated waveguide (SIW) techniques are proposed. The out-of-phase characteristic is achieved by employing multilayered SIW structures with sub-wavelength periodic slots on the top and bottom surfaces of SIW transmission lines. The validation of two designed filtering baluns shows satisfactory agreements between measured and simulated results. A prototype with a fractional bandwidth (FBW) of >66% is developed, and the circuital area of the SSPP-SIW filtering balun is decreased by 50% through the integration of HMSIW and SSPP configuration.

Summary: This paper proposes a wideband compact equal-length phase shifter based on the hybrid half-mode substrate integrated waveguide and spoof surface plasmon polariton concept. By etching half-butterfly grooves on the top conductor layer of the waveguide, the phase shift is compensated and a wideband response is achieved.

Summary: This paper presents a C-band filtering power divider (FPD) based on a hybrid of spoof surface plasmon polariton (SSPP) and half-mode substrate integrated waveguide (HMSIW). The proposed hybrid circuit is designed by etching subwavelength corrugated grooves in the HMSIW upper wall and has both characteristics of the SSPP and HMSIW structures. It can create the bandpass response and reduce both transverse and longitudinal dimensions of the substrate integrated waveguide structure by nearly 50%. The dispersion and transmission characteristics of the proposed HMSIW-SSPP transmission line are analyzed. The lower and upper edges of the passband can be adjusted independently by tuning the dimensions of the HMSIW and SSPP structures. The presented FPD is fabricated and measured to validate the proposed design procedure. The simulated and measured results are in good agreement. The measured results show that the proposed circuit achieves a bandwidth of 66% from 4 to 8 GHz with better than 10.5 dB return loss and a minimum insertion loss of 1.05 dB.

Summary: In this study, tunable mechanical-mode coupling based on nanobeam-double optomechanical cavities is proposed. The coupling of the excited optical mode with both symmetric and antisymmetric mechanical supermodes is mediated at a frequency of approximately 4.96 GHz. The mechanical-mode coupling is tuned through both optical spring and gain effects, and a reduced coupled frequency difference in non-Hermitian parameter space is observed. These results are significant for research on the microscopic mechanical parity-time symmetry for topology and on-chip high-sensitivity sensors.

Summary: In this study, a viable strategy to solve the problem of methicillin-resistant Staphylococcus aureus (MRSA) was identified by screening an antibiotic and non-antibiotic combination that broadens the antimicrobial spectrum. Chenodeoxycholic acid (CDCA) was found to synergistically act with carbapenem antibiotics to eradicate MRSA-related infections. The underlying mechanism was associated with the interaction of penicillin-binding proteins (PBPs), and CDCA sensitized MRSA to carbapenems by disrupting the cell membrane.

Summary: This study demonstrates a free-space optical multi-port beam splitter based on a polarization-independent all-dielectric metasurface. By applying an optimized phase-pattern paradigm, amorphous silicon metasurfaces are used to prepare multi-port beam splitter samples with arbitrarily predetermined output port number, power ratio, and spatial distribution. The experimental results show that the fabricated beam splitters can achieve high total splitting efficiency and beam-splitting fidelity within a certain bandwidth. Such proposed beam splitter provides great flexibility for optical integrated systems and diverse applications.

Summary: This research proposes a photonic-reconfigurable entanglement distribution network (PR-EDN) based on a silicon quantum photonic chip, which is crucial for realizing quantum internet. The entanglement resources are generated by a quantum light source array based on spontaneous four-wave mixing in silicon waveguides and distributed to different users through on-chip Mach-Zehnder interferometers with thermo-optic phase shifters. Experimental demonstrations show that the network topology of the PR-EDN can be reconfigured in three states by controlling the quantum interference through the phase shifters. In addition, a reconfigurable entanglement-based quantum key distribution network is realized as an application of the PR-EDN, which makes it suitable for future quantum networks requiring complex network control and management. Moreover, silicon quantum photonic chips show great potential for large-scale PR-EDN due to their capabilities for generating and manipulating plenty of entanglement resources.

Summary: Integrated quantum photonic circuit is a promising platform for future quantum information processing. To achieve large-scale quantum photonic circuits, the quantum logic gates applied should be as small as possible for high-density integration. In this study, supercompact universal quantum logic gates are implemented on silicon chips using the method of inverse design. The fabricated controlled-NOT gate and Hadamard gate are the smallest optical quantum gates reported so far. The designed quantum circuit, by cascading these fundamental gates, performs arbitrary quantum processing and is several orders smaller in size than previous quantum photonic circuits. This research paves the way for realizing large-scale quantum photonic chips with integrated sources, and can have important applications in the field of quantum information processing.
