Continuous-Wave Band Translation Between the Near-Infrared and Visible Spectral Ranges

Abstract

Abstract-Wavelength conversion based on degenerate fourwave mixing in a photonic crystal fiber with two zero-dispersion wavelengths is investigated both theoretically and experimentally. The proposed concept of universal band translation in a single-pass traveling-wave structure offers a wavelength band rather than a single-wavelength mapping between distant spectral ranges. Near-infrared signals are modulated using both harmonic and pseudorandom bit sequences and translated to the visible optical band. Multiple-channel translation, which produces wavelength-division-multiplexed idlers in the visible band, is demonstrated for the first time. The performance of the translation process is measured both spectrally and temporally for both single-and multiple-channel signals.

Parametric amplification and processing in optical fibers

“…18. Indeed, the first wavelength division multiplexing in visible [54], illustrated in Fig. 19, was demonstrated as a proof that PCF conversion could be used across the NIR band.…”

“…The overwhelming superiority of NIR technology is the result of three decades of communications research, which is unlikely to be replicated in any other spectral range. The visible optical band, while lacking such strong economic justification, offers a unique set of capabilities, such as the channel transport in ocean water [54].…”

“…19, was demonstrated as a proof that PCF conversion could be used across the NIR band. The first conversion [54] of a Gbps optical channel from NIR to visible has been demonstrated recently using a continuous-wave 800 nm band semiconductor pump and dispersion tailored PCF, and is illustrated in Fig. 20.…”

Optical signal processing by fiber-based parametric devices

“…In recent experiments with MSFs, MIs were used to generate sidebands whose wavelengths differed by 500 nm [17][18][19]. In other experiments with MSFs, MI was used to generate idlers whose wavelengths differed from the input-signal wavelengths by 1000 nm [20][21][22], as shown in Figs. 3 and 4.…”
