B. Caron et al., PHOTODIODES SELECTION FOR THE VIRGO DETECTOR THE FIRST STEP, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 360(1-2), 1995, pp. 379-384
In the framework of the gravitational waves detector VIRGO, we are dev
eloping the photo detectors system. The diodes we will use must satisf
y at the same time quite unusual criteria, among them a good quantum e
fficiency at a wavelength of 1.06 mu m and a good linearity at MHz fre
quencies for an incident light power of 100 mW. We present here the te
st method and the first very promising results we obtained towards the
se directions with commercially available diodes in InGaAs.
