We have demonstrated all-optical frequency down- and up-conversion of MHz-bandwidth OFDM signals compliant with the IEEE 802.16e WiMAX wireless standard The cavity, built on a silicon chip and supporting a breathing-like mechanical resonance at 3.9 GHz, performs simultaneously as nonlinear mixer and local oscillator when operated in the phonon lasing regime.
The results have been published in Laser & Photonics Reviews: https://onlinelibrary.wiley.com/doi/full/10.1002/lpor.202100175.
