“…This function can be utilized for wavelength conversion [21]. A multi-band transmission scheme was proposed with inter-band wavelength conversion using an OPA [22]. The WDM signals of the C-band are converted to the L-band and S-band on the transmitter side, and they are converted back to the C-band on the receiver side.…”

“…The transmission of 240-ch. 200-Gbps signals over 100 nm within S-, C-, and Lbands using only C-band transponders was demonstrated using FOPAs [22]. Furthermore, for a flexible multi-band network, a configuration in which optical wavelength conversion is performed in optical nodes is also being studied [40].…”

“…Utilizing this function of the OPA, wavelength conversion of signal light can be performed [21]. To achieve multi-band optical transmission, a system configuration using wavelength conversion by OPA has been proposed, and WDM transmission with this configuration using triple bands of the S-, C-, and L-bands was recently demonstrated [22]. Also, idler light is characterized by being a phase-conjugated copy of input signal light.…”

The optical parametric amplifier (OPA) has attractive features for optical communications, such as a wideband, high gain, and fast transient response. In addition, by using idler light, which is phase-conjugated light generated in the amplification process, various kinds of optical signal processing, such as fiber-nonlinearity mitigation, wavelength conversion, and phase-sensitive amplification, can be performed. A periodically poled LiNbO3 (PPLN) waveguide is an χ (2) -based optical parametric amplification medium, and it makes both wideband and high-gain amplification possible. We developed a 4-port PPLN module that can combine signal light and pump light into a PPLN waveguide with low loss. In this paper, we overview the applications of OPA to WDM optical fiber transmission and explain the configurations of an OPA using 4-port PPLN modules. As applications of our PPLN-based OPA, we introduce the demonstration of wideband inline amplification exceeding 5 THz. Furthermore, we demonstrate inter-band wavelength conversion between C-and S-bands using PPLN waveguides developed for multi-band optical transmission applications.

“…Realizing this configuration requires a wideband OPA medium exceeding the 8-THz amplification band. Recently, PPLN-based OPA and high-nonlinear-fiberbased OPA that meet this requirement have been demonstrated [4][5][6]. In order to arrange channels in S-band, additional transponders and wideband inline amplifiers covering C-and S-bands are required.…”

“…Extending the optical amplification bandwidth by upgrading optical repeaters, which typically consist of standard erbium-doped fiber amplifiers (EDFAs) with a 4-THz bandwidth, is attractive to increase the capacity at the deployed-fiber link. Transmission experiments involving the use of an optical bandwidth of over 10-THz have been conducted based on hybrid Raman/EDFAs [1,2], all-Raman amplification [3], and additional optical-band utilization such as S-, C-and L-bands [4][5][6]. A semiconductor optical amplifier with over-100-nm continuous bandwidth was developed and demonstrated as a discrete optical amplifier [7].…”

This paper proposes an optical parametric amplifier (OPA), as an inline-repeater, using a periodically-poled-LiNbO3 (PPLN) waveguide with over-10-THz amplification bandwidth, and also presents wide-band wavelength-division-multiplexing (WDM) inline-amplified transmission with the OPA. Our PPLNbased OPA is polarization-independent and has a spectrally efficient configuration by filtering phase-conjugated signals (idlers). We implemented our PPLN-based OPA with half its ideal configuration with an over-10-THz amplification bandwidth because of the limited number of PPLN waveguides. The implemented OPA had 5.125-THz amplification bandwidth, gain of beyond 15 dB, and noise figure of less than 5.1-dB. The gain excludes the 5.6-dB loss of an idler rejection filter employed in the transmission experiment so that the implemented OPA can compensate 9.5-dB link loss of transmission fibers and optical components. A 3 × 30.8-km inline-amplified transmission with 41channel 800-Gbps WDM signal in 125-GHz spacing was successfully demonstrated using our PPLN-based OPA as an inline-repeater. The results also indicate that the OPA's amplification bandwidth can potentially be extended to 10.25 THz.
