In our data-driven era, solving complex problems efficiently is crucial. However, traditional computers often struggle with this task when dealing with a large number of interacting variables, leading ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240077 , discusses agile cavity ringdown spectroscopy enabled by moderate optical feedback to a quantum cascade laser. Optical ...

Semiconductor lasers exhibit a rich array of dynamical behaviours when subject to optical feedback. Reflected light from an external cavity re-enters the gain region, altering carrier and photon ...

Based on optical-feedback cavity-enhanced absorption spectroscopy (OF-CEAS) technology, a research team led by Prof. Zhang Weijun from the Hefei Institutes of Physical Science (HFIPS) of the Chinese ...

Regardless of its color, an LED's light output varies as a function of forward current and ambient temperature. As Figure 1 shows, an LED's light output can vary by as much as 150% over its ...
