An ultra-broadband photonic-chip-based parametric amplifier - Nature
An optical parametric amplifier based on integrated photonic circuits fabricated using low-loss gallium phosphide-on-silicon dioxide demonstrates improved bandwidth and gain performance over state-of-the-art erbium-doped fibre amplifiers while maintaining a low noise figure.

I've been writing about squeezed light based on some curiosity triggered by my phd work on multimode traveling wave parametric amplifier research; two years ago i planned to write a book on "Measuring Beyond the Quantum Limit : Squeezed Light"

some of the fun and surprising stuff one can learn from Quantum Optics is the following:
- spontaneous emission is stimulated emission by zero point vacuum fluctuations
- Maxwells equations are true up to the single photon level
this story of light is so fascinating
- spontaneous emission is stimulated emission by zero point vacuum fluctuations
- Maxwells equations are true up to the single photon level
