Title:
SPATIAL LIGHT PHASE MODULATOR AND OPTICAL COMPUTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/153286
Kind Code:
A1
Abstract:
In order to provide a spatial light phase modulator that can be miniaturized and that is operable at high speed, each microcell (C) of this spatial light phase modulator (13) is composed of a magnetization free layer (C11) and a control unit (electrode C12) that controls the magnetization direction (arrow M11) of the magnetization free layer (C11). The magnetization free layer (C11) and the control unit (electrode C12) are configured to control the magnetization direction (arrow M11) so as to be parallel or substantially parallel the direction (arrows kf, kr) of a normal to the first optical effective surface and the second optical effective surface (bottom surfaces C111, C112).
