How do the different modulation schemes compare in terms of performance and applications? Thus, we need to have a general idea of which modulation scheme is appropriate for a particular application. Amplitude modulation is straightforward in terms of implementation and analysis. Also, AM waveforms are fairly easy to demodulate.

Coherent detection in lightwave transmission systems can improve receiver sensitivities by dB over direct detection sensitivities.

In phase-shift-keyed PSK systems the information is impressed on the phase of the optical field while the amplitude is held nominally constant. A phase-modulated PM optical wave with no amplitude modulation propagating in an optical fiber will be adversely affected by group velocity dispersion in the fiber. In particular, the various frequency components of the PM wave will arrive at the end of the fiber at slightly different times.

This causes amplitude modulation of the received signal which in turn leads to a penalty in coherent transmission systems. Andrew R Chraplyvy, R. Tkach, L. Buhl, and Rod C. Delavaux and R. BUHL, T.

Comparing and Contrasting Amplitude, Frequency, and Phase Modulation

Terahertz THz science and technology promise unique applications in high-speed communications, high-accuracy imaging, and so on. To keep up with the demand for THz systems, THz dynamic devices should feature large phase shift modulation and high speed. To date, however, only a few devices can efficiently manipulate the phase of THz waves. In this paper, we demonstrate that efficient phase modulation of THz waves can be addressed by an active and enhanced resonant metamaterial embedded with a nanostructured 2D electron gas 2DEG layer of a GaN high electron mobility transistor HEMT. The enhanced resonant metaunit couples the traditional dipolar and inductance-capacitance resonances together to realize a coupling mode with enhanced resonance. In addition, given the high-speed modulation ability of the HEMT, this concept provides a promising approach for the development of a fast and effective phase modulator in THz application systems.
