Abstract
We demonstrate wideband flat bright-soliton Kerr-comb in thin-film foundry-compatible SiN platform. This is achieved using multi-segment coupled resonators. Multi-segment coupling with optimized coupling regions allow higher order dispersion engineering, paving the way toward wideband flat Kerr-comb around the pumping frequency. Here, using three coupling regions, we report a design based on thin-film SiN with 3dB spectral coverage of 3.8 THz around the pumping wavelength λ0 = 1550 nm.
