Helping you to model realistic quantum photonic devices

Replace costly physical prototypes with our modelling software. Quantillion can shorten the optimisation process from 26 weeks to 2 and decrease costs by 90%.

Ey Component Animation — Time evolution of the *E_y* component of the optical spin excitation mode propagating in a nonlinear optical waveguide filled with an ensemble of four-level resonant absorbers.

Ez Component Animation — Time evolution of the *E_z* component of the optical spin excitation mode propagating in a nonlinear optical waveguide filled with an ensemble of four-level resonant absorbers.

S13 Animation — Energy-level population inversion in one pair of a 2-by-2 coupled four-level system upon excitation with an ultrashort pulse.
