Abstract:
An optical pulse generator having a high order transfer function, the pulse generator comprising:a) a first interferometric modulator comprising an optical input, an electrical input, a first arm, a second arm and an optical output; and b) a second interferometric modulator comprising an optical input, an electrical input, a first arm, a second arm and an optical output, the second interferometric modulator being optically coupled into the second arm of the first interferometric modulator, wherein the optical output of the first interferometric modulator generates pulses at 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 first 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.
