Abstract :
We propose a new version of electro-optic sampler at 1.5 mum, which uses an ion-irradiated InP-based photoconductor for the optical-to-electrical conversion. A measurement bandwidth larger than 300 GHz is obtained for a signal-to-noise ratio higher than 15 dB and excitation pulses of peak amplitude as high as 0.81 V. The performances of our system are validated from test measurements performed on coplanar waveguide transmission lines made on semi-insulating InP substrates
