High‐Isolation LCoS‐Based Optical Switch with Phase Hologram Parameter Optimization

open access: yesAdvanced Photonics Research, EarlyView.
A 1 × 9 liquid crystal on silicon (LCoS)‐based optical switch is experimentally demonstrated, revealing that the worst‐case port isolation exceeds 37 dB within the wavelength range of 1460–1540 nm. This work offers an alternative route for the development of optical switches with a large number of ports and high isolation, applicable to large‐capacity ...

Ultralow Loss Coupling Tuning of Photonic Accelerators

open access: yesAdvanced Photonics Research, EarlyView.
A polymer material cured by electron beam is used to perform precise and ultralow loss tuning on photonic accelerators made for highly efficient computation. The versatility of the technique is demonstrated on a large number of directional coupler devices with varying initial coupling ratios and application on a crossbar array for matrix multiplication

Evaluation of Absorbent Solutions for the Integrated CO2 Desorption and Electrolysis

open access: yesAdvanced Sustainable Systems, EarlyView.
Integrated CO2 electrolysis combines desorption and electrolysis to reduce costs and emissions. This study identifies KOH and piperazine as effective absorbents, providing sufficient electrochemically accessible CO2 and compatibility with cell conditions.

Template‐Free Fabrication of Single Atom Fe‐Based Cathodes Unlock High‐Performing Anion‐Exchange Membrane Fuel Cells

open access: yesAdvanced Science, EarlyView.
A high‐performance single‐atom critical‐raw‐material (CRM)‐free Fe‐based catalyst is designed using a template‐free manufacturing approach. This single‐atom catalyst (SAC) is incorporated into operando anion‐exchange membrane fuel cells using O2 and CO2‐free air displaying excellent performance.
