Nanobolometer on a silicon chip — Image of the power sensor on a silicon chip. The measured radiation arrives from the horizontal transmission line on the left and the power level is read out using the line of the right. The red line is used to apply a known heater power to calibrate the power reading. the inset on the right shows a zoom-in of the absorber and thermometer parts of the device.
