[Study of luminescence ability of organic white light emitting diode by light conversion].

An organic luminescence material of white light was investigated. The organic luminescence film was made by heating and melting method. The film consists of riboflavin, anthrone derivative, and linear low-density polyethylene.

[Influence of initial chirp on the evolution of spectra].

The influence of dispersion and nonlinearity on the spectra was analysed. The nonlinear Schrödinger equation was solved numerically in the frequency domain. The effect of the initial chirp on the spectra of different formats was simulated.
