Optically monitored and distortion-free delay of optical pulses

摘要

The method involves operating a wave guide in successive level by coupling of pumping radiation, and adjusting the pumping radiation according to characteristics. Stimulated brillouin scattering is originated in wavelength range of optical pulse. The pumping radiation is coupled with the wave guide opposite to propagation direction of optical pulse that is modified by another pumping radiation. Overall linear characteristic of a complete system is resulted from sequence of two levels to maintain the optical pulse to be delayed. An independent claim is also included for an optical signal delaying system including a source.
