- Abstract
- Disclosed is a multi-channel optical signal generating apparatus, which includes a CW laser that generates a single optical signal, an optical signal processor unit that processes the single optical signal, an oscillator that generates an electrical signal, and an electrical signal processor unit that generates a modulation signal, based on the electrical signal, and the optical signal processor unit includes ‘n’ optical circulators, at least one optical intensity modulator, (m-1) optical phase modulators, and ‘n’ BiODLs, the electrical signal processor unit includes a RF power divider which divides the electrical signal, and ‘m’ RF power amplifiers, the RF power divider divides the electrical signal into ‘m’ divided electrical signals, and the optical signal processor unit modulates and outputs the single optical signal by the at least one optical intensity modulator and the (m-1) optical phase modulators, based on the ‘m’ divided electrical signals divided from th
