Title:
OPTICAL PHASE MODULATOR, OPTICAL DEVICE, AND OPTICAL ARITHMETIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/163753
Kind Code:
A1
Abstract:
With a view to providing an optical phase modulator that is compact in size and capable of operating at high speed, this optical phase modulator (11) is provided with: a block (13) which constitutes a magnetization free layer; and a first electrode (electrode 16) which is indirectly provided to a first surface (surface 131) of the block (13).
