US 2026/0267175 A1 · HYBRID MODE MULTIPLEXING OPTICAL MODULATOR

Abstract

An optical modulator including at least one electrode and a waveguide is described. The waveguide includes a mode multiplexer, a modulation section, and a mode converting reflector. The modulation section is between and proximate to a portion of the electrode(s). The modulation section is in an optical path between the mode multiplexer and the mode converting reflector. The mode multiplexer is configured to propagate a first mode from a first waveguide arm to the modulation section, to receive a second mode from the modulation section, and to provide the first mode to a second waveguide arm from the second mode received from the modulation section. The mode converting reflector is configured to receive the first mode from the modulation section and to propagate the second mode back through the modulation section.
