Photonic band-gap inhibition of modulational instabilities

Gomila, Damià and Zambrini, Roberta and Oppo, Gian-Luca (2004) Photonic band-gap inhibition of modulational instabilities. Physical Review Letters, 92 (25). pp. 253904-1. ISSN 0031-9007

Spatial structures as a result of a modulational instability are studied in a nonlinear cavity with a photonic crystal. The interaction of the modulated refractive index with the nonlinearity inhibits the instability via the creation of a photonic band gap. A novel mechanism of light localization due to defects and pattern inhibition is also described.
