Patent number: 10690850Abstract: A method and apparatus for simultaneously modulating at least two distinct characteristics of an optical carrier propagating in an optical waveguide with at least two electrical signals includes transmitting an optical beam that includes the optical carrier into an optical waveguide defined in electro-optic material, and applying the at least two electrical signals at the same time to generate an electric field in the optical waveguide. The instantaneous predominant orientation of the electric field in the optical waveguide generated by the applied at least two electrical signals depends on the relative instantaneous values of the applied electrical signals. The at least two distinct characteristics of the optical carrier propagating in the optical waveguide are simultaneously and independently modulated depending on the predominant orientation of the electric field in the optical waveguide as a result of the application of the at least two electrical signals.Type: GrantFiled: July 24, 2018Date of Patent: June 23, 2020Assignee: Phase Sensitive Innovations, Inc.Inventors: Janusz Murakowski, Timothy Creazzo
