The demonstrated QCMs can reconstruct holographic images and display diffraction patterns simultaneously. Silicon nanofins are arranged in the Penrose tiling pattern as illustrated by the 2D color ...

Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3. It has found numerous applications spanning from ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...
