{"version":"1.0","type":"link","title":"Self-phase modulation - Newikis","description":"Self-phase modulation (SPM) is a nonlinear optical effect of light–matter interaction. An ultrashort pulse of light, when travelling in a medium, will induce a varying refractive index of the medium due to the optical Kerr effect. This variation in refractive index will produce a phase shift in the…","provider_name":"Newikis","provider_url":"https://newikis.com","cache_age":86400}
