We demonstrate broadband spectral phase conjugation based on temporal imaging via four-wave mixing and show for the first time compensation of pulse distortions due to second- and third-order dispersion and self-phase modulation.
We demonstrate single-shot optical sampling using a time lens based on four-wave mixing in a silicon nanowaveguide. The eye diagram for an 80-Gb/s data is characterized at 1.3 TS/s sampling rate using a 5-GHz oscilloscope.
In this paper, a technique is used to temporally compress entire data packets instead of isolated pulses using a temporal imaging system. Experimentally, 24-bit non-return to zero (NRZ) packets at 10 Gb/s is encoded and then temporally compress the packets to a data rate of 270 Gb/s using two optical time-lenses based on four-wave mixing (FWM) in silicon- on-insulator nanowaveguides. This packet compression...
We demonstrate four-wave mixing in silicon nitride waveguides with -7.1 dB conversion efficiency between the signal and idler. We observe no evidence of nonlinear losses with pump powers as high as 110 W.
We demonstrate ultra-broadband low-peak-power frequency conversion of continuous-wave light in a silicon photonic structure via four-wave mixing. Our process produces continuous conversion over two-thirds of an octave from 1241-nm to 2078-nm wavelength light.
We demonstrate significant reduction of one of the main nonlinear loss mechanisms in silicon waveguides-free carrier absorption. We show reduction of the free-carrier lifetime from 3 ns down to less than 12.2 ps.
We demonstrate a temporal imaging system that allows simple synchronization to an external clock by using a spectrally broadened time-lens-based pump laser. We integrate this pump laser into an ultrafast oscilloscope scheme and demonstrate 2 ps resolution with 130 ps record length.
We demonstrate 160-Gb/s wavelength conversion across 21 nm in the C-band using four-wave mixing in dispersion-engineered silicon photonic waveguides. Measurements show a conversion efficiency of -15.5 dB and a pulse broadening factor of 38%.
We demonstrate parametric oscillation in a complementary metal-oxide-semiconductor (CMOS) compatible silicon nitride ring resonator. We generate up to 40 wavelengths with a threshold power as low as 50 mW.
We demonstrate frequency magnification by a factor of 105 using a spectral imaging system with two four-wave mixing based time-lenses. We achieve a 1-GHz frequency resolution.
We present ultra-broadband wavelength conversion in silicon photonic waveguides at a data rate of 40 Gb/s. The dispersion-engineered device demonstrates a conversion bandwidth spanning the entire S-, C-, and L-bands of the ITU grid. Using a continuous-wave C-band pump, an input signal of wavelength 1513.7 nm is up-converted across nearly 50 nm at a data rate of 40 Gb/s, and bit-error-rate measurements...
We demonstrate for the first time wavelength multicasting performed in a silicon photonic chip. We investigate multicast number selectivity at 40-Gb/s data rates and evaluate each configuration using BER measurements, establishing immense prospect for scalability.
We demonstrate a novel technique for high-speed characterization of optical signals based on temporal magnification using four-wave mixing in a silicon nanowaveguide. Sampling at 1.3 TS/s is demonstrated with a 5-GHz oscilloscope.
We demonstrate compression of 24-bit 10-Gb/s NRZ data packets to 270 Gb/s using a temporal telescopic system. This technique's versatility allows format-transparent compression of packets (i.e. NRZ, RZ, DPSK) and analog waveforms by arbitrary factors.
