Document Type and Number:
WIPO Patent Application WO/2023/233669
Kind Code:
A1
Abstract:
This optical calculation device comprises a plurality of stages each having one or more Mach-Zehnder interference-type light switches. The optical calculation device causes input light, of which the phase has been changed by a predetermined phase amount, to be inputted in accordance with the position of the input light in an input stage at which light is inputted, and causes the input light to propagate in accordance with a control electric signal.
