Mid-infrared optical waveguides: missing link of integrated photonics
T Toney Fernandez, Yongsop Hwang, Dale Otten +2
Lack of low phonon energy glass waveguides delays the progress of integrated photonics in the mid-infrared wavelength. This perspective provides insights on the history of waveguid…
