Phase-sensitive amplification (PSA) is a nonlinear optical interaction providing attractive functionalities for all-optical classical and quantum signal processing with a wide range of promising applications, such as regeneration of high modulation formats [1] and amplification of entangled single-photon sources [2]. To exploit PSA in a scalable and compact implementation, this technique has been...
We report an integrated, CMOS-compatible source of multiple and independent photon pairs at different wavelengths compatible with standard fiber communication channels and quantum memories. It operates in a self-locked mode with no external pump laser.
Raman scattering can be exploited for amplification in optical fiber telecommunications or, chemical identification in spectroscopy, but represents a source of detrimental noise photons for quantum communications. The spectral distribution of spontaneous Raman scattering (SpRS) can be measured in bulk samples with the free-space 90° scattering method [1]. In long fibers the SpRS spectra can be measured...
We present a dissipative four wave mixing tunable laser based on a integrated CMOS-compatible high-Q nonlinear ring resonator, emitting subpicosecond pulses at 200GHz-repetition rate. Quasi-sinusoidal 800GHz emission regime is also demonstrated.
We present a subpicosecond, 200 GHz-repetition rate, passively mode-locked laser based on high-harmonic four-wave mixing in an integrated CMOS-compatible high-Q nonlinear ring resonator.
We present the first system penalty measurements for all-optical wavelength conversion via four wave mixing in an integrated, CMOS compatible, ring resonator, obtaining < 0.3 dB system penalty at 2.5Gb/s for ∼22dBm average pump power.
