  Optical control of chirality in chiral superconductors bears potential for
future topological quantum computing applications. When a chiral domain is
written and erased by a laser spot, the Majorana modes around the domain can be
manipulated on ultrafast time scales. Here we study topological superconductors
with two chiral order parameters coupled via light fields by a time-dependent
real-space Ginzburg-Landau approach. Continuous optical driving, or the
application of supercurrent, hybridizes the two chiral order parameters,
allowing one to induce and control the superconducting state beyond what is
possible in equilibrium. We show that superconductivity can even be enhanced if
the mutual coupling between two order parameters is sufficiently strong.
Furthermore, we demonstrate that short optical pulses with spot size larger
than a critical one can overcome a counteracting diffusion effect and write,
erase, or move chiral domains. Surprisingly, these domains are found to be
stable, which might enable optically programmable quantum computers in the
future.
