Abstract :
In the framework of the gravitational waves detector VIRGO, we are developing the photo detectors system. The diodes we will use must satisfy at the same time quite unusual criteria, among them a good quantum efficiency at a wavelength of 1.06 μm and a good linearity at MHz frequencies for an incident light power of 100 mW. We present here the test method and the first very promising results we obtained towards these directions with commercially available diodes in InGaAs.
