发明名称 Amplification of interleaved optical signals
摘要 A technique for generating a data signal and a beacon signal for free space optical communications involves generating a data signal having a first optical wavelength and a beacon signal having a second optical wavelength. The data signal is encoded with data via modulation at a first modulation rate. The beacon signal is an inverted version of the data signal and can be further modulated at a second modulation rate that is less than the first modulation rate. The data and beacon signals are optically combined to produce a combined signal in which power attributable to the beacon signal is interleaved with and substantially non-overlapping temporally with power attributable to the data signal. The combined signal is amplified via a fiber amplifier, and the combined signal is supplied to transmitter optics for transmitting the data signal and the beacon signal into free space.
