Microfluidic memristive oscillators as universal logic gates for neuromorphic computing.

Conical microfluidic channels filled with electrolytes exhibit volatile memristive behavior, offering a promising platform for energy-efficient, neuromorphic computing. Here, we integrate theoretical models of these iontronic channels as additional nonlinear elements in nonlinear Shinriki-inspired oscillators and demonstrate in simulations that they exhibit alternating chaotic and non-chaotic dynamics across a broad frequency range. Exploiting this behavior, we construct XOR and NAND gates by coupling three "Memriki" oscillators, and we further realize the full set of standard logic gates through combinations of NAND gates.

Broadband Packaged Erbium-Doped Polycrystalline AlO Waveguide Amplifier with 24 dB External Net Gain.

We present a packaged erbium-doped waveguide amplifier (EDWA) based on polycrystalline AlO, demonstrating high external fiber-to-fiber gain, stable performance over a broad wavelength range, and robustness to temperature variations. The device was integrated with fiber arrays and thermoelectric control, facilitating efficient characterization and practical deployment. With bidirectional pumping at 1480 nm, a 50 cm long waveguide amplifier achieves an external net gain of 24 dB and an off-chip output power exceeding 54 mW at 1550 nm.

Monolithically integrated erbium-doped polycrystalline AlO waveguide amplifier on silicon photonics platform.

We demonstrated the monolithic integration of a polycrystalline AlO:Er waveguide amplifier onto the passive SiN TriPleX platform, enabling high-performance on-chip amplification for photonic integrated circuits. The polycrystalline AlO:Er was deposited using reactive magnetron co-sputtering, ensuring compatibility with large-scale fabrication. On-chip wavelength division multiplexers, based on directional couplers, enabled the combining and splitting of the pump and signal powers on-chip.

Scalable erbium-doped waveguide amplifier with external fiber-to-fiber gain using reactively sputtered polycrystalline aluminium oxide.

We demonstrate reactively sputtered polycrystalline AlO:Er waveguide amplifiers exhibiting external fiber-to-fiber net gain, broadband amplification, and low noise figure. With an erbium concentration of 1.5 × 10 ions/cm, a 30 cm amplifier length, and bi-directional pumping at 1480 nm, > 14 dB of external gain at 1550 nm is shown with off-chip output powers of over 56 mW measured at the output fiber, as well as sustained gain across 60 nm of bandwidth.

Intelligent soft matter: towards embodied intelligence.

Intelligent soft matter lies at the intersection of materials science, physics, and cognitive science, promising to change how we design and interact with materials. This transformative field aims to create materials with life-like capabilities, such as perception, learning, memory, and adaptive behavior. Unlike traditional materials, which typically perform static or predefined functions, intelligent soft matter can dynamically interact with its environment, integrating multiple sensory inputs, retaining past experiences, and making decisions to optimize its responses.
