Abstract
Embodiments of the disclosure pertain to an optical modulator including an m*n optical coupler, first and second waveguides coupled or connected to the m*n optical coupler, a first phase shifter coupled to the first waveguide, and first and second loop mirrors at respective ends of the first and second waveguides opposite from the m*n optical coupler. The m*n optical coupler is configured to combine substantially similar or identical continuous light beams (at least one of which may be phase-shifted) returned through the first and second waveguides by the first and second loop mirrors to form a modulated optical signal. A compound optical modulator, a modulated or modulatable laser, and methods of using and manufacturing the optical modulators, are also disclosed.
