Cavity mode manipulated by single gold nanoparticles

APL Photonics, 2020
The ability to manipulate microlaser performance is highly desirable so as to promote on-chip classical and quantum information-processing technology. Here, we demonstrate that mode manipulation of bottle microresonators is enabled by precise deposition ...

Numerical experiments with single mode gyrotron equations

Mathematical Modelling and Analysis, 2012
Gyrotrons are microwave sources whose operation is based on the stimulated cyclotron radiation of electrons oscillating in a static magnetic field. This process is described by the system of two complex differential equations: nonlinear first order ...

Mode Optimization and Polarization Control in VCSELs with Sub-Wavelength Gratings

IEEE Photonics Journal
We have demonstrated the integration of sub-wavelength gratings (SWG) into a 795 nm vertical cavity surface emitting laser (VCSEL) with inverse surface relief to achieve coordinated control of the mode and polarization. At a grating period of around 0.5 &
