Synopsis: Domenii: Electronics: Electronics colaterale: Bandwidth:

To this end, photodetectors with an extremely narrow bandwidth are required, which only respond to particular wavelengths.

This particular detector has a bandwidth of only six nanometres (nm. This means its bandwidth is five times narrower than that of a comparable photodetector.

The device is also sensitive to polarised light, which helps to reduce the scattered background radiation.

A large number of photodetectors, with very narrow bandwidths, is necessary so as to simultaneously detect as many different substances as possible.

An optical biosensor works by absorbing a specific bandwidth of light and shifting the spectrum

Currently plasmonic absorbers used in biosensors have a resonant bandwidth of 50 nanometers said Koray Aydin assistant professor of electrical engineering and computer science at Northwestern University's Mccormick School of engineering and Applied science.

It is significantly challenging to design absorbers with narrower bandwidths. Aydin and his team have created a new nanostructure that absorbs a very narrow spectrum of light#having a bandwidth of just 12 nanometers.

This ultranarrow band absorber can be used for a variety of applications including better biosensors. We believe that our unique narrowband absorber design will enhance the sensitivity of biosensors Aydin said.
