Title:
PHOTONIC SPIN REGISTER, INFORMATION WRITING METHOD, AND INFORMATION READ-OUT METHOD
Document Type and Number:
WIPO Patent Application WO/2022/158545
Kind Code:
A1
Abstract:
A photonic spin register (100) comprises: a shift register unit (104) having a magnetic material layer (124) of a shape extending in one direction; a light receiver (114) for receiving a serially input, pulse amplitude-modulated optical signal (PL) and converting the optical signal into an optical current (Iph); and a spin Hall element (106) electrically connected to the light receiver (114) and stacked on the magnetic material layer (124) in a partial region thereof, the spin Hall element (106) exhibiting the spin Hall effect when the optical current (Iph) from the light receiver (114) flows therethrough. When the optical current (Iph) flows through the spin Hall element (106), a spin orbit torque acts on the magnetic order of the magnetic domains of the magnetic material layer (124), whereby spin information is written. When a shift current (Is) is flown in one direction through the shift register unit (104), domain walls move in the magnetic material layer (124), whereby the spin information written to the magnetic domains is moved and buffered in the magnetic material layer (124).
