Self-induced transparency (SIT) is a kind of coherent transient phenomena in two-level atomic system. The optical pulse with an area that is an integer multiple of 2π, which causes SIT in an absorber, is stable and a kind of soliton. Thus SIT is expected to be useful in pulse compression and pulse shaping. In this paper, we discuss some problems in experiments of SIT and surveys the experimental results of SIT. It is also described the recent experimental results of coherent nonlinear pulse propagation in BiI3 crystal using tunable sub-picosecond pulses.

A theoretical analysis is made of the possibility of using self-induced transparency in constructing neuristor logic circuits. It is shown that under certain conditions collisions between 2π pulses result in their annihilation. This, together with other properties of the self-induced transparency effect, makes it possible to use 2π pulses as carriers of unitary information in optical neuristor circuits.
