Abstract:
Fluorescent antennas have emerged as promising alternatives to conventional lens modules in optical wireless communication (OWC) systems, offering an expanded field of view (FOV) by surpassing the étendue limit. However, their limited anti-interference performance in both time and frequency domains has constrained their widespread applications. Herein, we introduce a novel “laser antenna” that integrates stimulated emission from high-quality perovskite microlasers into the optical antenna design. Achieving a theoretical bandwidth of up to 36.2 GHz and a signal-to-noise ratio (SNR) of up to 40 dB, this laser antenna demonstrates strong anti-interference capabilities in the temporal domain. Furthermore, spectral analysis using amplitude shift keying (ASK) modulation reveals its distinct periodicity, tunability, and recoverability, enabling robust frequency selectivity even in the presence of interference. These findings establish the laser antenna’s potential to overcome critical limitations of conventional OWC systems, thereby paving the way for efficient, stable, and high-performance optical wireless links.

Abstract:
Solar concentrators laterally converge solar energy to the side of architectural glass and are attractive candidates for building-integrated photovoltaics. Present available luminescent-type and scattering-type solar concentrators suffer from omnidirectional waveguide induced low efficiency, coloring/hazing restrained aesthetic quality, and poor compatibility with existing architectural glass. Here, we propose a diffractive solar concentrator via directly coating cholesteric liquid crystal (CLC) layers onto the architectural glass. The stacked CLC layers with submicron lateral periodic alignment enable broadband and unidirectional waveguiding inside the glass, and thus supply a high-efficient platform for transmissive solar energy capturing with merits of high aesthetic quality and economic viability. A 1-inch-diameter prototype powers a 10-mW fan outdoors, and a typical 2-m-wide window is calculated to concentrate solar energy by 50 times. The design is expected to bring a global terawatt-scale green energy supply and billion-ton annual carbon emission reduction, meeting with the sustainable development of human society.

Abstract:
Surface-emitting optoelectronic devices such as vertical cavity surface emitting lasers are important for various applications. However, the devices are typically grown on expensive and small-size III-V substrates. Si substrates can offer much improved scalability, lower cost and higher thermal properties but present significant challenges such as the formation of crystalline defects from the heteroepitaxial growth of III-V semiconductors on Si. Here, we propose multifunctional metamorphic In0.1Ga0.9As/AlAs distributed Bragg reflectors (DBRs) on Si which serve as a bottom mirror with a high reflectivity of 99.8% while simultaneously reducing the crystalline defect density by a factor of three, compared to GaAs/AlAs DBR on Si. The proposed DBR structure also exhibits a crack-free and exceptionally smooth surface morphology with root-mean-square roughness of 1.2 nm, which is five times smoother than the conventional GaAs/AlAs structure on Si. Furthermore, as proof of concept, InAs quantum dot surface-emitting diodes are fabricated on the metamorphic III-V DBR/Si templates and their performances are analyzed in comparison to those grown on native GaAs wafers. A narrow electroluminescence linewidth of 11.5 meV is observed, confirming that the multifunctional metamorphic DBR is promising for a scalable and more techno-economic surface-emitting III-V optoelectronics grown on Si substrates.

Abstract:
Miniaturized spectroscopy techniques show great potentials in on-site applications, with most progress focused on manipulating the spectral responses of either dispersion elements or detectors. Little attention was paid on light sources, while light source and its optical collimation unit left unsaid in most miniaturized spectrometers actually dominate a majority of the footprint and the cost of the entire platform. Here, we demonstrate light-source engineering as a new paradigm for developing a miniaturized spectroscopic sensing platform in mid-infrared (MIR), where spectral information of the analyte is encoded in the MIR image of a chip-size thermal source. An array of angle-insensitive metasurface sub-emitters that operate at various wavelengths enables a straightforward sensing method by decoding an image of the radiation intensity distribution. Accurate and robust classification of organic solvents and drug sorting, as well as quantitative concentration measurement of mixed organic solutions, were experimentally demonstrated with an imaging angle tolerance up to 40º. Moreover, spectral imaging was explored using this device, achieving distinct images of a plastic covered steel ring. By integrating the functions of light source, dispersion element and collimation unit in conventional spectroscopy platforms into such a chip-size metasurface thermal emitter, the proposed miniaturized MIR spectral sensing technique shows promising potential for portable and on-site material analysis.
