H. Schmidt et Rj. Ram, All-optical wavelength converter and switch based on electromagnetically induced transparency, APPL PHYS L, 76(22), 2000, pp. 3173-3175
We propose a method for all-optical switching and wavelength conversion usi
ng electromagnetically induced transparency (EIT). We discuss the mechanism
for the transfer of information in this scheme and determine the condition
s for which NxN wavelength conversion can be realized. We compare the prope
rties and limits of an EIT-based switch to conventional wavelength converte
