We demonstrate near-field radiative heat transfer between nanostructures and show that it dominates over other on-chip conduction channels. The measured heat transfer behavior matches the predictions of boundary element method simulations for parallel nanobeams.
We report the first demonstration of a broadband optical isolation using a Silicon nanowaveguide via Bragg scattering four-wave mixing. We achieve an isolation ratio of 4 dB over a bandwidth of 8 nm.
We experimentally demonstrate a FWM-based receiver operating at long wavelengths. The scheme successfully demultiplexes a 1866-nm 40-Gb/s NRZ signal into 10-Gb/s tributaries while simultaneously wavelength-converting it to 1320 nm for photodetection.
We generate optical frequency combs spanning 75 THz with a 204-GHz spacing using parametric oscillation in an integrated silicon-nitride microring resonator. The comb spacing is uniform to better than 5.2×10−11 relative to the optical frequency.
