摘要
Communications Systems particularly suited for manipulating stimulated Brillouin scattering (SBS), or similar tunable laser amplification effects, to acheive improved means for selecting an optical signal from many such signals carried on a single fiber. This disclosure also describes means for producing a tunable, spectrally-narrow line to power this laser amplification. The disclosure also describes an improved polarization-sweeping device which allows the system to handle variable polarization of signals, when necessary. It also discloses other subsystems and apparatus facilitating the optimum signal-tapping process, including heterodyning procedures, a low-band-width channel- indentification means, and a new laser, all particularly useful in the system described. The laser is also useful in other systems where a tunable, spectrally narrow, stable source is required.
