A compact laser scanner that scans approximately 90° has been demonstrated, which is enabled by an electrothermal MEMS mirror encapsulated in a 3D printed holder with a curved dome for optical amplification.
This paper reports a 3-dimensional (3D) micro-optical coupling system for improving coupling efficiency in the Littrow configured micro-electro-mechanical system (MEMS) tunable lasers. In the coupling system, an optical fiber acts as a rod lens for light convergence in the vertical plane, while a deep-etched silicon parabolic mirror confines the light in the horizontal plane. Compared with previous...
This paper reports an integrated injection-locked laser constructed using microelectromechanical systems (MEMS) technology, which achieves a large wide locking range of 43 nm with an average SMSR of 32 dB.
We report plasmonic Fabry-Perot nano-cavities formed by high aspect ratio metal mirrors on a metal surface. Quality factors from 100-200 were obtained, limited by plasmonic losses and fin scattering at short and long wavelengths respectively.
We use a simple set-up consisting of two multilayer mirrors and a hollow fiber EUV light source to obtain high-resolution EUV images. Magnifications of X20 and X50 are demonstrated
