High sensitivity photonic time-stretch electro-optic sampling of terahertz pulses
High sensitivity photonic time-stretch electro-optic sampling of terahertz pulses
Single-shot recording of terahertz electric signals has recently become possible at high repetition rates, by using the photonic time-stretch electro-optic sampling (EOS) technique. However the moderate sensitivity of time-stretch EOS is still a strong limit for a range of applications. Here we present a variant enabling to increase the sensitivity …
