The principle of timekeeping has been to count the repetitions or oscillations of repeating natural phenomena such as rotation of earth or movement of stars. Over the millennia a myriad of devices has been invented for timekeeping including pendulum or crystals, each with a period far shorter than the daily …

Between electronics and photonics there exists a frequency gap of approximately two octaves, i.e., the frequency range between 100 GHz and 10 THz, across which there are limited capabilities for signal generation, control, guidance, and processing. Researchers have demonstrated e that phonon-polaritons in ionic crystals like LiNbO3 or LiTaO3 may …
