A team of researchers from Tsinghua University have achieved phonon and photon lasing in a silicon-based optomechanical crystal cavity. This paves the way for the harnessing of the coherence of ...

The direct lasing outside the fluorescence spectrum is deemed impossible owing to the ‘zero-gain’ cross-section. However, when electron-phonon coupling meets laser oscillation, an energy ...

Planar microcavities with distributed Bragg reflectors (DBRs) host, besides confined optical modes, also mechanical resonances due to stop bands in the phonon dispersion relation of the DBRs.

"Think of phonon lasing as a counterpart to traditional optic, or photon lasing, with exciting applications in medical surgery, materials science and communications.

Quantum leap for phonon lasers Date: February 24, 2010 Source: American Physical Society Summary: Physicists have taken major step forward in the development of practical phonon lasers, which emit ...

Posted: Oct 28, 2015: A new physical mechanism allows 'phonon lasing' driven by optical forces at ambient conditions (Nanowerk News) Last years have witnessed a steady and fast increase in the number ...

Lasing Beyond Light. Physicists focus on whole new types of waves, ... And phonon lasers vault the technology out of the electro­magnetic spectrum altogether, creating coherent beams of sound.

At a threshold pump power, phonon gain exceeds phonon loss resulting in phonon lasing. (Bottom) Phonon amplification in a superlattice. Tunneling of electrons from one quantum well to the next is ...
