ABSTRACT:
An optical pulse position modulator includes a substrate with parallel first and second sides, the substrate including a first waveguide channel and a parallel second waveguide channel orthogonal to the first and second sides, a linear chirped grating orthogonal to and upon the first and second waveguide channels, and at least a first electrode along the first waveguide channel to apply a voltage modulation thereto. A first optical circulator has a first port coupled to a pulsed optical carrier signal, and a second port coupled to the first waveguide channel on the first side of the substrate, and a second optical circulator has a fourth port coupled to the third port of the first optical circulator, and a fifth port coupled to the second waveguide channel on the second side of the substrate. An output of the second waveguide channel is a position modulated optical pulse signal.
