WebbThe choice of MgO as a substrate is based on three reasons: its refractive index is lower than that of the PT, hence the feasibility of a planar waveguides, the small difference of the lattice mismatching (7.7% [17]) and the thermal expansion coefficients [18] allows epitaxial growth with good PT/ MgO interface. millennial views of revelation
