Graphene Photodetectors

Graphene PhotodetectorsGraphene photodetectors from Emberion Oy convert light to an electronic signal using graphene charge transducers combined with a nanocrystal light absorber.

The photodetectors provide responsivity and low noise over a broad spectral range from VIS to NIR/SWIR wavelengths without cooling below room temperature. The full dynamic range is 160 dB, owing to the low noise and an unsaturated response.

The photodetectors are packaged into a standard TO-8 can with a built-in thermoelectric cooling for thermal stabilization. The size of the rectangular photosensitive active area is tailorable. Potential applications include spectrometry, optical gas detection or optical power measurements. The photodetectors are offered as digital modules — circuit boards comprising hardware and software implementation for calibration, signal preprocessing, analog-to-digital conversion and digital input/output. Photodetectors are also available as discrete analog components.
