CIRCUIT WITH PASSIVE COMPONENTS FOR THE ULTRA-QUICK CONTROL OF AN OPTOELECTRONIC DEVICE

摘要

The invention relates to a circuit for the ultra-quick control of an optoelectronic device, characterised in that said circuit includes a generator of voltage pulses having a pulse duration of less than 400 ps, and a circuit (17) for shaping control pulses comprising: an output suitable for being connected in series to a line terminal (13) of the optoelectronic device, and an input connected to the voltage-pulse generator and receiving the voltage pulses formed by the latter, between a terminal of said input and a terminal of said output, mounted in parallel in relation to one another: a first branch (20) made up of a passive rectifier circuit (22a, 22b) having non-zero threshold voltage and, in series in the first branch in forward direction relative to said line terminal (13) of the optoelectronic device, a second capacitive branch (21).
