摘要： A power amplifier is provided, which includes a power dividing unit, a first power amplification tributary, a second power amplification tributary, and an impedance conversion unit. Input ends of the first power amplification tributary and the second power amplification tributary are coupled to two output ends of the power dividing unit respectively. An output end of the first power amplification tributary is coupled to an output end of the second power amplification tributary through the impedance conversion unit. Rated power of a peak power amplifier in the second power amplification tributary is greater than that of a main power amplifier in the first power amplification tributary. The beneficial effects of the present invention lie in that larger back-off exists at the peak of an efficiency curve of the power amplifier, and in the case that power is back-off, efficiency of the power amplifier is improved.

摘要： A number of embodiments provide multi-Wavelength Laser Source (MWLS) designs based on Super Continuum (SC) generation using Highly Non-Linear optical Fiber (HNLF). Advantageously, in some embodiments this technology only needs a single wavelength locking mechanism to tune and lock the whole set of channels to the ITU grid. Furthermore, in some embodiments, this laser system is able to provide wavelength channels in all the S, C and L bands. In this design, the optical signal provided by an initial seed laser source goes through a wavelength channel multiplier stage based on HNLF and is expanded in the frequency domain to cover a wider wavelength range. The wavelength channel multiplier consists of a number of optical fibers including various combinations of HNLF, single mode fiber and dispersion shifted fibers.
