Chip-based Brillouin processing for carrier recovery in coherent optical communications
Elias Giacoumidis, Amol Choudhary, Eric Magi +8
Modern fiber-optic coherent communications employ advanced spectrally-efficient modulation formats that require sophisticated narrow linewidth local oscillators (LOs) and complex d…
Lossless integrated RF photonic filter with record-low noise figure and 116 dB of dynamic range
Yang Liu, Jason Hotten, Amol Choudhary +2
We report a silicon nitride RF photonic notch filter with unprecedented performance including 8 dB of RF gain, record-low noise figure of 15.6 dB, and spurious-free dynamic range o…
High quality waveguides for the mid-infrared wavelength range in a silicon-on-sapphire platform
Fangxin Li, Stuart D. Jackson, Christian Grillet +10
We report record low loss silicon-on-sapphire nanowires for applications to mid infrared optics. We achieve propagation losses as low as 0.8dB/cm at 1550nm, 1.1 to 1.4dB/cm at 2080…
High speed optical processing via four-wave-mixing in a silicon waveguide
F. Li, M. Pelusi, D-X. Xu +4
We demonstrate all-optical demultiplexing at 160 Gigabits per second in the C-band, based on nonlinear optics using four-wave mixing (FWM) in a silicon nanowire. We achieve error-f…
