摘 要: 首次从理论上研究了非相干线性白光孤子在强非局域非瞬时Kerr介质中的传输特性。这种非相干白光孤子具有椭圆高斯形式的光强分布和各向异性的时空相干特性。当孤子存在时,其低频率组分的空间相干距离应比高频率组分的空间相干距离要大。入射功率及光束的相干特性决定了非相干线性白光孤子的传输特性。当光束的入射功率不满足孤子稳定传输的临界值时,非相干光束将会产生线性的谐振。本文对相关特性作了详细的讨论。
关 键 词: 无线电物理;非相干白光孤子;强非局域介质;互频谱密度理论

Abstract: This paper proposes a theoretical investigation of the propagation property of incoherent accessible white-light solitons in strongly nonlocal media with noninstantaneous Kerr nonlinearity. These solitons have elliptic Gaussian intensity profile and anisotropic spatiotemporal coherence properties. When this soliton exists, the spatial coherence distance should be longer for lower frequencies and shorter for higher frequencies. The propagation of the incoherent accessible white-light solitons depends on the incident power as well as the coherence properties of the beam. When the incident power differs from the critical value, the accessible white-light solitons will yield the periodic harmonic oscillations. This paper discusses the coherence properties in detail.
Key words: radio physics; incoherent white-light solitons; strongly nonlocal media; mutual spectral density theory
