All-optical versus electro-optical quantum-limited feedback

All-optical versus electro-optical quantum-limited feedback.

Quantum state protection using all-optical feedback

An all-optical feedback scheme in which the output of a cavity mode is used to influence the dynamics of another cavity mode is considered. We show that under ideal conditions, perfect preservation against decoherence of a generic quantum state of the source mode can be achieved.

All-optical quantum teleportation.

We propose an all-optical continuous-variable quantum teleportation scheme based on optical parametric amplifiers.

Quantum model for electro-optical amplitude modulation.

We present a quantum model for electro-optic amplitude modulation, which is built upon quantum models of the main photonic components that constitute the modulator, that is, the guided-wave beamsplitter and the electro-optic phase modulator and accounts for all the different available modulator structures. General models are developed both for single and dual drive configurations and specific r...

Negative Feedback Semiconductor Optical Amplifiers and All-Optical Triode

The field of optical communications is moving toward the realization of photonic networks with wavelength division multiplexing (WDM) utilizing the full bandwidth of optical fibers. Conventionally, an erbium-doped fiber amplifier (EDFA) and a semiconductor optical amplifier (SOA) are used for amplifying an optical signal in optical communications. SOAs can contribute to this and offer the key a...
