Digital holography (DH) has emerged as one of the most effective coherent imaging
technologies. The technological developments of digital sensors and optical elements have …

A disordered photonic medium is one in which scatterers are distributed randomly. Light
entering such media experiences multiple scattering events, resulting in a “random walk” …

Chirality refers to a geometric phenomenon in which objects are not superimposable on
their mirror image. Structures made of nanoscale chiral elements can exhibit chiroptical …

Since its invention in 1994, the quantum cascade laser (QCL) has emerged as a versatile
light source of wavelength 4–12 µm, covering most of the mid-and long-wavelength infrared …

Laser diodes are efficient light sources. However, state-of-the-art laser diode-based lighting
systems rely on light-converting inorganic phosphor materials, which strongly limit the …

Lasers possess many attractive features (eg, high brightness, narrow linewidth, well-defined
polarization) that make them the ideal illumination source for many different scientific and …

The capacity of self-healing fields to reconstruct after passing through scattering media may
prove useful in reducing speckle formation. Here, we study the speckle response of the …

Fourier‐based optical computing operations, such as spatial differentiation, have recently
been realized in compact form factors using flat optics. Experimental demonstrations …

We report a novel method for fabrication of three-dimensional (3D) biocompatible micro-
fluidic flow chambers in polydimethylsiloxane (PDMS) by 3D-printing water-soluble polyvinyl …

This manuscript presents the design and initial application of a mid-infrared laser-absorption-
imaging (LAI) technique for two-dimensional (2D) measurements and tomographic …
