ABSTRACT
In this work, continuous-wave broadly tunable simultaneous generation of red (650–690 nm), green (520–575 nm), and blue (425–495 nm) light in aperiodically poled Zn-diffused LiNbO[sub 3]:Er[sup 3+]/Yb[sup 3+] channel waveguides is reported after Ti:sapphire excitation in the 850–990 nm range. The red and green emissions arise from energy transfer and upconversion mechanisms between Yb[sup 3+] and Er[sup 3+] ions, while the blue light with a maximum efficiency of 0.04% W[sup -1] cm[sup -1] is produced by quasi-phase matching processes. © 2003 American Institute of Physics.
