Abstract
We observe guided blue and green upconversion fluorescence in an ion-exchanged waveguide that is fabricated in an erbium–ytterbium-codoped silicate laser glass. The guides are opticallypumped at room temperature by using a Ti:sapphire laser with λ = 880–980 nm; the observed fluorescence is in two bands, 480–490 and 520–560 nm, and results from multiphoton excitation.
