Abstract We propose a scheme for the realization of optical transparency by using a periodically modulated optical coupler with losses in one waveguide. We discover that the increase of the transparency can be achieved only by varying the parameters of modulation, and such modulation-enhanced transmission is the consequence of phase transition of the quasi-energy spectrum. Our findings offer an efficient way to manipulate light transmission in realistic dissipative systems.
