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 the RF power divider.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
