Several schemes have been proposed to implement all-optical transistors. In many cases, a proof of concept has been experimentally demonstrated. Among the designs are those based on:

* [[electromagnetically induced transparency]], where the transmission
** ofin an [[optical cavity]] or amicroresonator, microresonatorwhere the transmission is controlled by a weaker flux of gate photons<ref>{{cite doi|10.1126/science.1238169}}</ref><ref>{{cite doi|10.1364/JOSAB.30.001329}}</ref>

** in free space, i.e., without a resonator, by addressing strongly interacting [[Rydberg state|Rydberg states]]<ref>{{cite 10.1103/PhysRevLett.113.053601}}</ref><ref>{{cite 10.1103/PhysRevLett.113.053602}}</ref>

* a system of indirect [[exciton]]s (composed of bound pairs of [[electrons]] and [[electron hole|holes]] in double [[quantum well]]s with a static [[dipole moment]]). Indirect excitons, which are created by light and decay to emit light, strongly interact due to their dipole alignment.<ref>{{cite doi|10.1063/1.4866855}}</ref><ref>{{cite doi|10.1364/OL.35.001587}}</ref>
