Simultaneous QPSK-to-2×BPSK wavelength and modulation format conversion in PPLN
IEEE Photonics Technology Letters, 2014Co-Authors: Francesco Da Ros, Kjeld Dalgaard, Yutaka Fukuchi, Michael Galili, Christophe PeucheretAbstract:Phase-sensitive cascaded second-harmonic generation and difference-frequency generation in a periodically poled lithium niobate waveguide allow converting two orthogonal Quadratures of an optical field to different wavelengths, thus enabling simultaneous quadrature phase-shift keying-to- 2×binary phase-shift keying modulation format and wavelength conversions. Static phase-sensitive extinction ratios above 20 dB are obtained for both Quadratures, resulting in error-free dynamic operation with low penalty (BER 1e−9) at 10 Gbaud.

simultaneous qpsk to 2 times bpsk wavelength and modulation format conversion in ppln
IEEE Photonics Technology Letters, 2014Co-Authors: Francesco Da Ros, Kjeld Dalgaard, Yutaka Fukuchi, Michael Galili, Christophe PeucheretAbstract:Phase-sensitive cascaded second-harmonic generation and difference-frequency generation in a periodically poled lithium niobate waveguide allow converting two orthogonal Quadratures of an optical field to different wavelengths, thus enabling simultaneous quadrature phase-shift keying-to- \(2\times \) binary phase-shift keying modulation format and wavelength conversions. Static phase-sensitive extinction ratios above 20 dB are obtained for both Quadratures, resulting in error-free dynamic operation with low penalty (BER \(10^{-9}\) ) at 10 Gbaud.

qpsk to 2 bpsk wavelength and modulation format conversion through phase sensitive four wave mixing in a highly nonlinear optical fiber
Optics Express, 2013Co-Authors: Francesco Da Ros, Kjeld Dalgaard, Lei Lei, Christophe PeucheretAbstract:A phase-sensitive four-wave mixing (FWM) scheme enabling the simultaneous conversion of the two orthogonal Quadratures of an optical signal to different wavelengths is demonstrated for the first time under dynamic operation using a highly nonlinear optical fiber (HNLF) as the nonlinear medium. The scheme is first optimized with respect to the power levels and phases of the four phase-coherent pumps. The successful modulation and wavelength conversion of the two complex Quadratures of a quadrature phase-shift keying (QPSK) signal to two binary phase-shift keying (BPSK) signals is then demonstrated experimentally with no power penalty at a bit-error-ratio (BER) of 10(-9) compared to direct interferometric demodulation of the QPSK signal.
