具有线性耗散和局域增益介质中的孤子

Solitons in a medium with linear dissipation and localized gain

Dmitry A. Zezyulin, Yaroslav V. Kartashov, Vladimir V. Konotop

摘要:

我们提出了在具有局域增益和均匀线性耗散的介质中的各种耗散孤子和呼吸模。该系统具有许多不寻常的性质,如聚焦和散焦介质中的指数局域模,在负传播常数值下聚焦介质中存在模式,当增益景观具有两个局部极大值时同时存在稳定的对称和反对称局域模,以及存在稳定的呼吸解。

英文摘要:

We present a variety of dissipative solitons and breathing modes in a medium with localized gain and homogeneous linear dissipation. The system posses a number of unusual properties, like exponentially localized modes in both focusing and defocusing media, the existence of modes in focusing media at negative propagation constant values, the simultaneous existence of stable symmetric and anti-symmetric localized modes when the gain landscape possesses two local maxima, as well as the existence of stable breathing solutions.
