Engineers have created a
deep-ultraviolet (UV) laser using
semiconductor materials
that show great promise for improving
the use of UV light for
sterilizing medical tools, among
other applications. The aluminum
gallium nitride-based device
is capable of emitting a
deep-UV laser at sought-after wavelengths and modal line widths.
The team used molecular beam epitaxy, a crystal growth technique,
to grow a high-quality crystal of aluminum nitride.
The second challenge was to create an optical cavity from the
stacked layers that could be used to trap the emitted light and
promote stimulated emission, which is necessary for the laser.
The cavity was created in the form of a small, micron-scale resonator
on an aluminum nitride chip.
The laser was able to achieve peak gain at a wavelength of
284 nm and modal line widths on the order of 0.1 nm. The line
width is an order of magnitude more precise than similar devices
and demonstrates the growth method's applicability toward
improved ultraviolet light emitters.

Precision matters.
n Pulse Signal Sensor Patch

wearable sensor patch thinner than a
hair strand that can measure pulse
wave signals with high precision. The
patch was printed using inkjet printing.
Using this technology, wearable
electronic devices can be made by
simply printing conductive ink on a
very thin substrate.
The team fabricated a pressure sensor that mimics skin's
tactility and used it to enable physical pulse waves to be detected
by the patch just as they are detected by the fingers.
The researchers also used a patch-type device with 100 sensor
pixels to obtain a two-dimensional (2D) pressure map on
the wrist.
The researchers successfully created a 2D pressure map to
accurately obtain the pulse wave signals and analyzed their
strengths to locate the invisible arterial blood vessels. Moreover,
they developed sensor patches of various sizes by taking
age, gender, and body sizes into consideration.
The newly developed technology allows for at-home diagnosis
of diseases that are usually performed only at hospitals.
