N2 - An optical Bragg-like microcavity can be formed when extremely short light pulses interacting coherently withthe medium collide in the resonant medium. Here we present an analytical approach, based on the approximatesolution of the time-dependent Schrödinger equation, that reveals both the cavity formation and its control by thehalf-cycle pulses colliding in the medium. This approach allows the calculation of cavity properties in the weakfield regime without the need for complex numerical simulations. Beyond the approximate analytical solutions,our analytical results are confirmed by numerical simulations of the Maxwell-Bloch equations. Grating formationis also studied in the strong-field regime, where collisions of self-induced transparency half-cycle pulses occur.The results presented here reveal, to our knowledge, a new type of spatio-temporal photonic crystal in the form ofmicro-cavities in a simple atomic medium. The results obtained demonstrate the feasibility of attosecond opticalswitching in a simple atomic medium with half-cycle pulses.
