- who: Zhen Wang from the whether the absorption coefficient or the refractive index of the material is changed to modulate the light beam, optical modulators can be classified as either absorptive or refractive type To date, commercial optical modulators are mainly established on waveguide-integrated devices with silicon-on-insulator and silicon-on-lithium-niobate configurations. However, their use is limited in the telecom NIR region due to strong material absorption at longer wavelengths. Now, writing in Light: Advanced Manufacturing, a sister journal of Light: Science and Applications, Prof. Wei Jin and his team from the Hong . . .
