We demonstrate an integrated, CMOS compatible, multiple wavelength source based on hyper-parametric oscillation via MI (FWM) gain in a high index doped silica glass ring resonator. We obtain lasing with wavelength spacings from 200 GHz to > 6 THz, with a threshold of 54 mW. This device has promise for telecommunications and on-chip WDM optical interconnects for computing.
We show that temporal pulse compression can be achieved by using an integrated, low dispersion, high index glass (Hydexreg) waveguide. Sub-ps compression is demonstrated for peak powers lower than 100 W using a 45 cm spiral waveguide.
By exploiting the excellent nonlinear properties of a novel silica based low-loss high index glass (Hydex reg), we demonstrated low peak power, efficient ps pulse compression in a 45 cm spiral waveguide.
We demonstrate four-wave-mixing with <5 mW CW pump power in high-index, doped silica glass micro-ring resonators. We also demonstrate efficient self-phase modulation for pulses with <100 W peak power, with negligible nonlinear absorption up to 25 GW/cm2.
We report wavelength conversion of ultra-low power CW light in integrated silica glass micro-ring resonators via four-wave-mixing in the C-band, as well as strong self-phase modulation of < 100 W peak power optical pulses in a 45 cm waveguide.
We present the first demonstration of ultra-low power four-wave-mixing in a high-index glass micro-ring resonator (47.5 mum radius). By using a mW-level CW pump power we obtained an appreciable wavelength conversion in the C-band.
Using self-phase modulation measurements, we show that high-index glass waveguides are a promising nonlinear platform given their ultra-low loss and high nonlinear Kerr response, determined to be 150 times larger than that of optical fibers.
