Design of Four-Wave Mixing Frequency-Shift-Free Amplitude Regenerators
Frequency-shift-free all-optical amplitude regenerators based on fiber-four-wave mixing were investigated by means of simulations. These regenerators, comprised of two stages of highly nonlinear dispersion-shifted fiber, were designed using a heuristic procedure that implements a routine based on a genetic algorithm to optimize the device performance. A bit error rate improvement of up to four ...
متن کاملAmplitude Shift Keying & Frequency Shift Keying
Aim: To generate and demodulate an amplitude shift keyed (ASK) signal and a binary FSK signal. Amplitude shift keying-ASK-in the context of digital communications is a modulation process, which imparts to a sinusoid two or more discrete amplitude levels. These are related to the number of levels adopted by the digital message. For a binary message sequence there are two levels, one of which is ...
متن کاملSuperresolution four-wave mixing microscopy.
We report on the development of a superresolution four-wave mixing microscope with spatial resolution approaching 130 nm which represents better than twice the diffraction limit at 800 nm while retaining the ability to acquire materials- and chemical- specific contrast. The resolution enhancement is achieved by narrowing the microscope's excitation volume in the focal plane through the combined...

متن کاملPolarization-insensitive optical spectral inversion without frequency shift based on four-wave mixing in semiconductor optical amplifiers
Two schemes for polarization-insensitive optical spectral inversion without frequency shift based on four-wave mixing are proposed, both utilizing a conventional semiconductor optical amplifier (SOA) and two pump waves. The significant advantages of the configurations include their simplicity, effective suppression of the signal and one of the pump waves and a reduction in the noise associated ...
