Abstract: Disclosed are a continuous wave supercontinuum laser source resonator using low-priced multimode semiconductor lasers as pumping light and applying a rare-earth doped optical fiber and a Highly Nonlinear Dispersion Shifted Fiber (HNL-DSF) to a ring resonator structure to embody a continuous wave supercontinuum light source, and a medical diagnostic apparatus using the same. The resonator consists of a pump combiner for inputting pumping light into the resonator; a rare-earth doped optical fiber for receiving and converting the pumping light into seed light of a predetermined wavelength band; a Highly Nonlinear Dispersion Shifted Fiber (HNL-DSF) for converting the light converted by the rare-earth doped optical fiber and oscillating in the resonator into a continuous wave supercontinuum laser source; and a coupler for outputting the supercontinuum laser source generated from the Highly Nonlinear Dispersion Shifted Fiber (HNL-DSF). Accordingly, it is possible to embody a simple and inexpensive continuous wave supercontinuum laser source.

Abstract: A method and apparatus to efficiently transmit data. The method and apparatus effectively aggregate data and transmit the data in a high-speed power line communication (PLC) network. The method of transmitting the data includes combining each of at least one or more data units transferred from an upper layer, with a field to indicate attribute information of the data unit, dividing the combined data units and fields into frame blocks of an identical size, and aggregating the divided frame blocks and transferring the aggregated frame blocks as one frame to a PHY layer. In this way, data units of a variety of types and sizes transferred from the upper layer are aggregated and transmitted as the one frame.
