MeV He ion-implanted planar waveguide in RTP crystal

The electronic structure of RbTiOPO4and the effects of the A-site cation substitution in KTiOPO4-family crystals

“…In particular, RTP is widely used in electro-optical and nonlinear optical devices due to its high optical damage threshold and high resistivity [2,[4][5][6][7][8][9][10]. Optical waveguide formation by ion-implantation and epitaxial techniques can be achieved in RTP, which is promising for the applications of RTP-based waveguide structures in integrated optics [11][12][13]. The crystal structure of RTP with a large unit cell containing 64 atoms is shown in figure 1 [4,14].…”
