An optical pulse generator having a high order transfer function that comprises a first and a second nested interferometric modulator, each modulator comprising an optical input, an electrical input, a first arm, a second arm and an optical output. The second interferometric modulator is optically coupled into the second arm of the first interferometric modulator . The optical output of the first interferometric modulator generates pulses a t a repetition rate that is proportional to a multiple of a frequency of an electrical signal applied to the electrical input of at least one of the fir st and second interferometric modulator and at a duty cycle that is inversely proportional to the order of the transfer function of the optical pulse generator. The multiple may be any integer equal to or greater than one.</SD OAB> |
