The resulting time-varying frequency, and thus varying phase of the vision carrier, is known as incidental phase modulation, ICPM. There are two basic types of circuits for demodulating ...

Relative to Vin2 and Vin1, the second modulator has an opposite phase relationship with its respective drain currents from U2D and U1B when compared to the first modulator. Therefore, we indeed have ...

Signal modulation is a mechanism which embeds an information-carrying signal into a carrier wave to broadcast information and is essential for high-speed communication. Zhonget al. report a ...

The plasmonic phase modulator was demonstrated at an operation speed of 40 Gbit s −1; its modulation frequency response was flat beyond 65 GHz. The modulator functioned over a 120-nm-wide ...

Complex light modulation—controlling light’s amplitude and phase—is key to many laser applications such as optical tweezers and holographic displays. To achieve such modulation at high ...

Columbia engineers have invented a breakthrough optical phase modulator that controls visible light—without dimming it—with the smallest footprint and lowest power consumption. New device will ...

The NIR-MPX-LN-0.1 phase modulator has become the reference component for many applications involving lasers such as spectrum broadening for suppression of the stimulated Brillouin back scattering ...

We can further build a circuit that provides a voltage controlled phase at the output, or that provides phase modulation. See Figures 29, 30, 31, and 32, which are “all-pass” phase-shifting circuits.
