Abstract
The present invention provides a fiber-based light source device, which includes a plurality of first, second or third light-emitting devices for respectively emitting a plurality of first, second or third lights, a plurality of first, second or third directional couplers for respectively coupling the first, second or third lights in their order so as to generate a first, second or third coupled light, a fourth directional coupler for coupling the first coupled light and the second coupled light so as to generate a fourth coupled light, and a fifth directional coupler for coupling the third coupled light and the fourth coupled light so as to generate an output light source. With coupling light beams from light-emitting devices and switching of those light-emitting devices in a sequential manner, the energy loss could be minimized and good heat dissipation could be obtained.

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.
