Article Abstract

The combination of wavelength division multiplexing (WDM) and mode division multiplexing (MDM) will increase the optical communication capacity significantly. In this configuration, we need multiple WDM devices serving as the inputs of the MDM device to excite modes at all the wavelengths. However, there is still no demonstration of integrated parallel WDM devices specifically designed for wavelength-mode hybrid multiplexing. Here, we propose and demonstrate a single 2 × 8 arrayed waveguide grating (AWG) for the multiplexing of 2 linearly polarized (LP) modes at 4 wavelengths with an MDM device. This parallel AWG concept can be further extended to support more wavelengths and introduce more spatial modes for high-capacity data transmission.

Silicon photonic MEMS switches based on split waveguide crossings.

The continuous push for high-performance photonic switches is one of the most crucial premises for the sustainable scaling of programmable and reconfigurable photonic circuits for a wide spectrum of applications. Conventional optical switches rely on the perturbative mechanisms of mode coupling or mode interference, resulting in inherent bottlenecks in their switching performance concerning size, power consumption and bandwidth. Here we propose and realize a silicon photonic 2×2 elementary switch based on a split waveguide crossing (SWX) consisting of two halves.

This study presents the design of a high-gain 16 × 16-slot antenna array with a low sidelobe level (SLL) using a tapered ridge gap waveguide feeding network for Ka-band applications. The proposed antenna element includes four cavity-backed slot antennas. A tapered feeding network is designed and utilized for unequal feeding of the radiating elements.

A wavelength demodulation method for ultra-short fiber Bragg grating (US-FBG) sensors based on an arrayed waveguide grating (AWG) and a convex optimization algorithm is proposed and demonstrated. Instead of measuring the output power ratio of the two adjacent AWG channels as previously done, in this work the wavelength demodulation is realized by reconstructing the US-FBG spectrum. The principle of spectral reconstruction involves using an AWG to sample the spectral information of US-FBG and constructing underdetermined matrix equations with the obtained prior information on transmission responses and the detected output power from multiple AWG channels.

Tunable Generation of Spatial Entanglement in Nonlinear Waveguide Arrays.

Harnessing high-dimensional entangled states of light presents a frontier for advancing quantum information technologies, from fundamental tests of quantum mechanics to enhanced computation and communication protocols. In this context, the spatial degree of freedom stands out as particularly suited for on-chip integration. But while traditional demonstrations produce and manipulate path-entangled states sequentially with discrete optical elements, continuously coupled nonlinear waveguide systems offer a promising alternative where photons can be generated and interfere along the entire propagation length, unveiling novel capabilities within a reduced footprint.

Scintillating Glass Fiber Arrays Enable Remote Radiation Detection and Pixelated Imaging.

Adv Mater

State Key Laboratory of Luminescent Materials and Devices, School of Materials Science and Engineering, South China University of Technology, Guangzhou, 510640, China.

The emerging metal halide perovskites are challenging the traditional scintillators in the field of radiation detection and radiography. However, they lack the capability for remote and real-time radiation monitoring and imaging in confined and hostile conditions. To address this issue, details on an inorganic scintillating glass fiber incorporating perovskite quantum dots (QDs) as highly efficient pixelated radiation emitters are reported, while the glass fibers themselves serve at the same time as low-loss waveguides, enabling long-distance and underwater X-ray detection.
