“…Their amorphous nature enables them to be both monolithically and heterogeneously integrated with a wide variety of materials at a low deposition temperature, compatible with the COMS back-end process. These remarkable material properties make them a viable platform for future multilayer optical communications systems [14][15][16][17][18][19][20][21][22][23], mid-infrared integrated photonic devices [22,24,25], sensors [26][27][28] and flexible photonic devices [29][30][31][32].…”

The interlayer coupler is one of the critical building blocks for optical interconnect based on multilayer photonic integration to realize light coupling between stacked optical waveguides. However, commonly used coupling strategies, such as evanescent field coupling, usually require a close distance, which could cause undesired interlayer crosstalk. This work presents a novel interlayer slope waveguide coupler based on a multilayer chalcogenide glass photonic platform, enabling light to be directly guided from one layer to another with a large interlayer gap (1 µm), a small footprint (6 × 1 × 0.8 µm3), low propagation loss (0.2 dB at 1520 nm), low device processing temperature, and a high bandwidth, similar to that in a straight waveguide. The proposed interlayer slope waveguide coupler could further promote the development of advanced multilayer integration in 3D optical communications systems.

We propose the use of the electro‐optic circuit to integrate with the short distance fiber optic loop network, which can be used to form the light fidelity (LiFi) network platform within the building. The electro‐optic conversion circuit is formed by a plasmonic circuit. It is a passive device consisting of an embedded plasmonic island within the microring conjugate mirror (MCM), in which the applied input‐output information can be connected to the fiber optic loop. In this design, all sources of the information can be coupled to the plasmonic transducer and connected to the network. The transducer mobility and two different wavelengths of the input sources are demonstrated and all port signals plotted. The free spectral range and the full‐width at half maximum at the center wavelength of 1.30 μm are ~370.0 and ~0.62 nm, respectively. This is equal to the bandwidth of ~77 PetaHz, from which the output intensity power is ranged between 5 and 15 mW (μm)−2. The linear relationship between the driven mobility and the input power of ~0.75 (cm)2. (Vs)−1 W−1 is achieved at the drop port, with the gold layer length is 600 nm.
