Modern communication systems often employ optical fibers to carry signals across or between devices, combining more than one function into a single circuit. However, signal transmission requires long optical fibers, which makes miniaturizing the device difficult. Instead of long optical fibers, scientists have started testing planar waveguides. In the Journal of Applied Physics, investigators report on a laser-assisted study of a type of glass that shows promise as a material for broadband planar waveguide amplifiers.

Molecules interact and align with each other as they self-assemble. This new simulation enables to find what molecules best interact with each other to build nanomaterials, such as materials that work as a nano electrical wire.
Roll-to-roll laser-induced superplasticity, a new fabrication method, prints metals at the nanoscale needed for making electronic devices ultrafast.
By doping alumina crystals with neodymium ions, engineers at the University of California San Diego have developed a new laser material that is capable of emitting ultra-short, high-power pulses -- a combination that could potentially yield smaller, more powerful lasers with superior thermal shock resistance, broad tunability and high-duty cycles.
Afsaneh Rabiei is pictured here with the device she developed that can capture scanning electron microscopy (SEM) images in real time at temperatures up to 1,000 degrees Celsius while applying stresses as high as two gigapascal.
