Learn how self-phase modulation SPM affects the spectrum and phase of a pulse propagating in a nonlinear medium. See examples of Gaussian pulses subject to SPM and the redistribution of energy in the frequency domain.

Self-phase modulation is ubiquitous in optical systems It provides foundational functionality to numerous photonic technologies, such as soliton generation and ultrafast pulse compression. However, it remains challenging to directly modify the coefficient of self-phase modulation, which is typically regarded as a fixed property of optical materials and structures.

Learn how self-focusing and self-phase modulation of light occur in optical materials with nonlinear index n2. See how spectral broadening, supercontinuum generation, and pulse compression can be achieved with Kerr nonlinearity and group velocity dispersion.

Self-phase Modulation in Semiconductors via Carrier Density Changes. The term self-phase modulation is occasionally used outside the context of the Kerr effect, when other effects cause intensity-dependent phase changes. In particular, this is the case in semiconductor lasers and semiconductor optical amplifiers, where a high signal intensity can reduce the carrier densities, which in turn

A review of self-phase modulation SPM and its applications in optical fibers, such as pulse compression, solitons, switching, and cross-phase modulation. Learn how SPM can be beneficial or detrimental for lightwave systems depending on the input pulse shape, chirp, and dispersion.

Self-phase modulation SPM is a nonlinear optical effect of light-matter interaction that causes a phase shift and frequency change in a pulse of light. Learn the theory, applications and examples of SPM in optical systems and media.

Self-phase modulation SPM is a nonlinear optical phenomenon that occurs when an intense laser beam passes through a medium, causing a change in the phase of the light due to its interaction with the material itself. This phenomenon is a result of the Kerr effect, which is the nonlinear response of a material to an electric field. Key points
