Quadrature phase shift keying (QPSK) modulators and binary phase shift keying (BPSK) modulators are used to change certain characteristics (amplitude, frequency or phase) of a carrier signal in order to transmit information. The changes in the parameter(s) of the carrier are made in accordance with an information-bearing signal (modulation signal).

I/Q modulators and I/Q demodulators change the amplitude, frequency, or phase of a carrier signal in order to transmit information. I/Q modulators split an incoming data stream into its in-phase (I) and quadrature (Q) components, mix the resulting signals with local oscillators that are 90º apart in phase, and then combine the outputs vectorially in a 0º mixer.

Optical modulators vary the amplitude and phase of a light beam; e.g., from a laser or by sound waves. Learn More about Optical Modulators

Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.g., band gap and index of refraction) of a material through which light is traveling, changing the characteristics of the light itself.
