In this study, we present a multidimensional inter-chip optical interconnect that employs polarization and mode division multiplexing techniques. We achieve per-wavelength data rates of up to 4×126 Gbps with NRZ-OOK and 4×196 Gbps with PAM-4 through the monolithic integration of high-speed GeSi electro-absorption modulators, grating-based (de)multiplexers, and a reconfigurable optical MIMO signal processor. By optically compensating for polarization rotation and mode mixing within a two-mode few-mode fiber connecting two photonic chips, we obtain inter-channel crosstalk levels below −20 dB . The optical MIMO processor exhibits an estimated thermal tuning energy of 0.14 pJ/bit and an estimated optical propagation latency of 0.14 ns. Furthermore, our system demonstrates transparency to modulation formats and symbol rates, effectively supporting both high-speed NRZ-OOK and PAM-4 transmission. These findings provide a promising pathway for the development of high-capacity, energy-efficient, and low-latency optical interconnects, essential for the next generation of AI and data center infrastructures.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"26 1","pages":"4500"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bidirectional mode-locked fiber lasers are especially attractive because of their compactness and strong common-mode-noise suppression. Yet deterministic and on-demand Δ f rep control remains a central challenge, since the counter-propagating pulses are dynamically coupled through common gain, saturable absorption, and nonlinear evolution, making a controllable differential response intrinsically difficult to establish. Here, we demonstrate an electrically controllable intracavity mechanism that enables deterministic and continuously tunable asymmetry in bidirectional pulse dynamics. By incorporating a voltage-controlled gold nanofilm saturable absorber, whose linear loss and saturable absorption can be simultaneously tuned, we induce unequal modulation of the counter-propagating solitons. As the applied voltage increases from 0 to 3 V, the wavelength difference increases from 2.68 to 3.65 nm, resulting in Δ f rep dynamic tuning from 424 to 583 Hz, corresponding to a 159 Hz tuning range. Numerical simulations reproduce the asymmetric spectral evolution and indicate that the effect originates from voltage-dependent intracavity transmittance and the resulting asymmetric intracavity gain dynamics. Importantly, the proposed scheme preserves the fully shared-cavity architecture while establishing an electrically controlled degree of freedom for on-demand tailoring of bidirectional soliton dynamics.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"37 1","pages":"4476"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, compact LWIR imaging systems are still limited by chromatic aberrations in wide-field-of-view (FOV) operation, which hinders simultaneous achievement of broadband performance, wide-field imaging, and system compactness. In response, we propose a field-dependent wavefront reconstruction method for compact LWIR hybrid lenses, establishing a direct link between wavefront evolution and imaging performance. Based on this approach, an aberration-corrected LWIR imaging system is demonstrated using a cascaded metasurface hybrid lens (CMHL) composed of a refractive lens and two metasurfaces. Achromatic imaging is achieved within the bandwidth of 8–12 μm across a 50° FOV. Especially, the total optical path length of the thermal camera is 14.12 mm measured from the entrance pupil to the charge-coupled device (CCD) sensor plane. Imaging performance is characterized using a 1951 USAF resolution target at a 20 cm object distance, resolving features corresponding to 2 lp/mm. This work provides a promising route toward compact high-performance infrared imaging systems and enables the integration of optical design, wavefront engineering, and computational imaging.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"61 1","pages":"4456"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The common frequency-correlated noise of the probe laser in different detection channels restricts the cross-spectral noise suppression and degrades sensitivity. We propose and experimentally demonstrate a dual-channel Rydberg heterodyne scheme based on asymmetric optical detuning. This method with cross-spectral density (CSD) processing reduces the interchannel probe-frequency noise correlation while preserving the common microwave-induced atomic response essential for signal coherence. Experimental results confirm that asymmetric detuning selectively suppresses laser-noise-induced coherence without degrading signal correlation and thus improves the signal-to-noise ratio (SNR). Compared with single-channel power spectral density (PSD) analysis, this method reduces the noise floor and improves the SNR by 12 dB for the resonant case and by 3.7 dB for the detuned case. These results provide a practical and readily implementable strategy for suppressing correlated technical noise in Rydberg heterodyne receivers, advancing the development of high-sensitivity electric-field metrology.","PeriodicalId":20048,"journal":{"name":"Photonics Research","volume":"78 1","pages":"4525"},"PeriodicalIF":7.6,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149089869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by the asymmetric auditory structure of owls, the DEA-LiNTF is designed with two asymmetric sensing ends, enabling two separated high-sensitivity fundamental in-plane resonance modes within a single device. The sensing performance of the DEA-LiNTF was systematically evaluated in lithium-niobate-enhanced photoacoustic spectroscopy (LiNPAS) and light-induced thermoelastic spectroscopy (LITES) systems. In the LiNPAS system, the 2 f signal amplitudes of DEA-LiNTF Mode 1 for methane ( CH 4 ) detection and Mode 2 for acetylene (C 2 H 2 ) detection are 5.25 and 7.16 times higher than those of the standard quartz tuning fork (QTF), respectively, achieving signal-to-noise ratio (SNR)-based minimum detection limits (MDLs) of 38.7 ppm and 10.5 ppm. In the LITES system, the corresponding signal enhancement factors reach 6.85 and 8.7, with SNR-based MDLs of 894 ppb and 252 ppb for CH 4 and C 2 H 2 , respectively. Crosstalk tests further confirm that the two resonance modes can operate independently under frequency-division multiplexing.
