Abstract

Reconfigurable electro-optic frequency shifters are provided. In various embodiments, the optical frequency shifter comprises a continuous optical spectrum medium; a discrete optical spectrum medium optically coupled to the continuous optical spectrum medium; and a tunable element operably coupled to the discrete optical spectrum medium, wherein: the discrete optical spectrum medium has N optical modes (I:{i. . . i}), said optical modes being ordered and equidistant in a frequency domain, wherein N is an integer equal to or greater than 3, each of the optical modes (i∈I) having a coupling constant κwith respect to the continuous optical spectrum medium, wherein at least one of the coupling constants κis different from the other coupling constants, the optical modes (I) having a coupling constant Ω with respect to one another, wherein the tunable element is configured to control the coupling constant Ω.
