Cross-phase modulation
open-in-new
<p>Cross-phase modulation (XPM) is a <a href="/facts/Nonlinear_optics/maerngXd">nonlinear optical</a> effect where one wavelength of light can affect the phase of another wavelength of light through the optical <a href="/facts/Kerr_effect/IoJN6wlW">Kerr effect</a>. When the optical power from a wavelength impacts the <a href="/facts/Refractive_index/yjkzvgeE">refractive index</a>, the impact of the new refractive index on another wavelength is known as XPM. </p>
