We propose and realize a packaged structure for the microcylinder–taper coupling system
by only gluing a glass tube and two glass plates together. Our package method avoids …

We present our results on an experimental and theoretical investigation into a glass
microsphere laser emitting at 2 μm wavelength. First, we fabricated Ho 3+-doped tellurite …

We propose and demonstrate a simple and reliable method for fabricating high-quality
whispering-gallery mode (WGM) optical microresonators in “mid-IR relevant” low-loss ZrF_4 …

Chalcogenide glasses constitute the only class of materials that remain fully amorphous
while exhibiting broad optical transparency over the full infrared region from 2-20 microns …

In recent years, compound glass microsphere resonator devices have attracted increasing
interest and have been widely used in sensing, microsphere lasers, and nonlinear optics …

A Nd^ 3+-doped tellurite-glass terrace microsphere was fabricated, and its laser
characteristics using free-space pumping were investigated. A localized laser heating …

The ability of optical whispering gallery mode (WGM) resonators to store energy in a very
small volume for a long time enables their use in practical applications as low-threshold …

Nd^ 3+-doped glasses are the most widely used laser gain media. However, Nd^ 3+-doped
non-silica microsphere lasers generally have lower quality (Q) factors due to the presence of …

A mid-IR lasing system based on a tapered fiber coupled to an Er 3+-doped microsphere
has been modeled and numerically investigated. In order to design and optimize the device …

The additive manufacturing (AM) family of techniques has been developed during the last
few decades. The techniques are used in order to fabricate 3D parts, layer-by-layer, directly …
