High-Performance Silicon-Based Multiple Wavelength Source
We demonstrate a stable CMOS-compatible on-chip multiple-wavelength source by
filtering and modulating individual lines from a frequency comb generated by a
microring resonator optical parametric oscillator.. We show comb operation in a
low-noise state that is stable and usable for many hours. Bit-error rate
measurements demonstrate negligible power penalty from six independent
frequencies when compared to a tunable diode laser baseline. Open eye diagrams
confirm the fidelity of the 10 Gb/s data transmitted at the comb frequencies
and the suitability of this device for use as a fully integrated silicon-based
WDM source.Comment: 3 pages, 3 figure
Dual-pumped degenerate Kerr oscillator in a silicon nitride microresonator
We demonstrate a degenerate parametric oscillator in a silicon-nitride
microresonator. We use two frequency-detuned pump waves to perform parametric
four-wave mixing and operate in the normal group-velocity dispersion regime to
produce signal and idler fields that are frequency degenerate. Our theoretical
modeling shows that this regime enables generation of bimodal phase states,
analogous to the \c{hi}(2)-based degenerate OPO. Our system offers potential
for realization of CMOS-chip-based coherent optical computing and an
all-optical quantum random number generator
