Leti develops tiny PIC sensors to detect gas

1:20 am PDT, March 20, 2019

Leti has developed prototypes  of centimetre-size portable optical sensors for chemical detection of gas.  The photo-acoustic sensors are based on mid-infrared photonic integrated circuits (MIR PICs). These silicon PICs, created by integrating optical circuits onto millimeter-size silicon chips, make extremely robust miniature systems, in which discrete components are replaced by on-chip equivalents. This makes them easier to ...
