  • System and method for generating an optical comb
    Patent number: 8724204
    Abstract: A system and method for generating an optical comb are provided. The system comprises at least one modulator for modulating a continuous wave sequentially by using at least one signal, respectively so as to generate a comb wave having a first plurality of subcarriers; and a nonlinear medium for causing the respective subcarriers of the comb wave to perform four-wave mixing to thereby generate a comb wave having a second plurality of subcarriers as the optical comb. With the present system and method, an ultra-wide spectrum optical comb with stable frequencies may be generated.

  • Signal transmission and reception device and method
    Patent number: 8693895
    Abstract: A signal transmission and reception device and method are provided. The transmission method comprises generating multiple optical carriers from a basic optical carrier; modulating optical carriers, except for a predetermined optical carrier, in the optical carriers by using multiple data signals respectively, to generate multiple optical modulated signals; and synthesizing the multiple optical modulated signals and the predetermined optical carrier into a single optical signal, and transmitting the signal.
