UC Davis electrical engineers have created a chip-sized device to measure the spectrum of visible and infrared light. The spectrometer-on-a-chip could have a wide range of applications in medicine, ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...

Red laser light is coupled into a spectrometer chip with an optical fiber from the left. The light travels along the chip until it is scattered out the the top in a waveguide section on the right.

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...
