“…The fist case is the socalled double sideband (DSB) operation in quadrature [10,12] that, due to the low harmonic distortion represents one of the most standard settings in analog communications. It is characterized by m 1 = m 2 = m, θ 1 = 0, θ 2 = π, ϕ B 1 = ϕ B 2 = π=2.…”

“…This is a well-known characteristic of this particular modulator design under classical operation. The second interesting operation regime is the single sideband (SSB) operation [12] in which by properly dephasing by 90 o one of the input RF modulating tones one of the RF sidebands (upper or lower) is eliminated at the output of the modulator. This operation mode is also of widespread use in analog communication due to its resilience to link dispersion, and represents a scattering device that maximizes the transition probability to a single (upper or lower) sideband mode in one of the two output ports.…”

Many components that are employed in quantum information and communication systems are well known photonic devices encountered in standard optical fiber communication systems, such as optical beamsplitters, waveguide couplers and junctions, electro-optic modulators and optical fiber links. The use of these photonic devices is becoming increasingly important especially in the context of their possible integration either in a specifically designed system or in an already deployed end-to-end fiber link. Whereas the behavior of these devices is well known under the classical regime, in some cases their operation under quantum conditions is less well understood. This paper reviews the salient features of the quantum scattering theory describing both the operation of the electro-optic phase and amplitude modulators in discrete and continuousmode formalisms. This subject is timely and of importance in light of the increasing utilization of these devices in a variety of systems, including quantum key distribution and single-photon wavepacket measurement and conformation. In addition, the paper includes a tutorial development of the use of these models in selected but yet important applications, such as single and multitone modulation of photons, two-photon interference with phase-modulated light or the description of amplitude modulation as a quantum operation.

“…In the link without an EDFA, the NF is about 50 dB, which is dominated by the link loss. Adding an EDFA causes signal-spontaneous beat noise, which dominates the noise figure [13]. However, the noise figure has been improved by 16 dB, which is due to the link gain.…”
