Abstract :
In the letter we describe improved ITO/GaAs photodiodes for very high-speed applications. For the first time a GaAs device is reported which combines a millimetric wavelength response with a ¿3dB bandwidth of ¿ 50 GHz (10 ps FWHM), with a high quantum efficiency in excess of 30% at 820 nm.
