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:{i1 . . . iN}), 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 (in∈I) having a coupling constant κe,n with respect to the continuous optical spectrum medium, wherein at least one of the coupling constants κe,n is 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.
