The development of ultra-broadband oscilloscopes is mainly governed by the needs of future telecom networks. But
other applications are requesting the availability of true real-time acquisition oscilloscopes. Systems able to be used in
single-shot operation are of prime interest for Inertial Confinement Fusion (ICF) and for the related R&D for plasma
We previously demonstrate a single-shot, 100GHz design of an all-optical sampling oscilloscope at 1μm (MULO). This
laboratory system has been improved in stability and compactness to make an all-in-one box prototype. More, by the
addition of an opto-electro-optics (OEO) sub-system at the input, we developed the ability to use this oscilloscope to
analyze an electrical input signal up to 60GHz. This new integrated subset also increases the range of wavelength for
optical input signal, from 300nm up to 2μm. Furthermore, it allows the use of inexpensive opto-electronic components at
telecom wavelength for this system regardless of the signal to be analysed. In parallel with these improvements, by
optimizing the heart of the system, we get a very high sampling rate, up to 500Gs/s and more; this allows considering
much higher bandwidths in the future.
In this talk, we will present latest developments and integration of this system. It will also allow us to give more details
on the innovative OEO sub-system.
