Apparatus and method to generate carrier suppressed-return to zero optical signal |
摘要 |
Provided are an apparatus and a method for generating a CS-RZ optical signal. The apparatus includes: a classifier distributing an input signal into two NRZ (non-return-to-zero) signals with an identical transmission speed; a first signal transformer converting one of the two NRZ signals into a first RZ signal using a full-frequency clock; a second signal transformer converting the other one of the two NRZ input signals into a second RZ signal using a full-frequency clock; a phase adjuster adjusting the first and second RZ signals so that a delay time corresponding to half a period of the input signal exists between the first and second RZ signals; a bias unit adding different DC (direct current) bias voltages to the first and second RZ signals; and a dual electrode optical modulator transforming the two electrical RZ signals into an optical CS-RZ signal.
