Direct imprinting of arbitrary spin helices using programmable structured light in a semiconductor two-dimensional electron gas
Precise control of spatial spin configurations, such as spin helices, is crucial for spin-based wave parallel computing. Conventional methods are constrained by fixed optical-grating periods and uniform light polarization, which restrict the ability to generate spin helices flexibly. This study offers an approach for programmable control of spin-helix periodicity and configuration that provides greater flexibility in tuning the wave number and configuration of spin textures. The technique promises significant advancements in spintronic and quantum information technologies by enabling more efficient generation and manipulation of spin textures.
