PT-symmetric phonon laser under gain saturation effect
(The Optical Society, 2020-07-20)
As an analog of optical laser, phonon laser has potential applications in various areas. We study a type of phonon laser implemented by two coupled micro-cavities, one of which carries optical gain medium. The phonon laser ...
Mechanical oscillations frozen on discrete levels by two optical driving fields
(American Physical Society, 2020-07-20)
We report a synchronization phenomenon which is simulated with an optomechanical system driven by two equally strong fields with different frequencies. Once the frequencies of the driving fields are properly matched, the ...
Semi-exact solutions of sextic potential plus a centrifugal term
(SPRINGER, 2020-11)
We revisit the one-dimensional quantum system of a sextic potential added with a centrifugal term, V(x)=ax(-2)+bx(2)+cx(4)+dx(6), where the parameters a,b,c and d are arbitrary. We find that its solutions can be expressed ...
Ultra-high optical nonreciprocity with a coupled triple-resonator structure
(IOP Publishing Ltd., 2021)
Optical transmission nonreciprocity as a widely investigated phenomenon is essential to various applications. Many sophisticated mechanisms have been proposed and tested for achieving the optical nonreciprocity on integrated ...
