Optical modulation can be categorized into two main types: direct (internal) modulation and external modulation. Direct modulation involves the direct manipulation of an optical source,
An optical modulator is a device which is used to modulate a beam of light. The beam may be carried over free space, or propagated through an optical waveguide (optical fibre).
An electro-optic modulator is a device which can be used for controlling the power, phase or polarization of a laser beam with an electrical control signal. It typically contains one or two Pockels cells, and
