Paper Abstract

We demonstrated that the wavelength range of lasing generated in optical loop amplifiers can be controlled by varying the reflection wavelength range of an add/drop filter. Controlling the lasing wavelength range enabled the gain to be precisely controlled relative to the input wavelength. The ring-down pulse waveform exhibits similar behavior to an optical memory when the lasing region is close to the input wavelength and it is exponentially attenuated when the region is far from the input. When the optical loop memory effect is optimized, a 200 ns optical pulse can be retained in the memory for 20 μs.
