Tapani Ryhanen, CEO of Emberion, said: 'Providing broad spectrum capabilities, without the expense of traditional InGaAs sensors, the VIS-SWIR graphene photodetector
provides a digital output using Emberion's in-house designed read out circuits --without the need to translate analogue data with additional components.'
Fujitsu Laboratories has now developed a semiconductor structure that can raise the operating temperature of the photodetector
without reducing its sensitivity compared to existing high-sensitivity infrared cameras.
