Fig. 1. (a) Geometric of the prepared Z-cut PPMgLN waveguide with a poling period of 10.2 μm, where w= 11.2 μm, h1 = 10.9 μm, h2 = 0.5 μm, and θ = 75.1°. (b) Characteristic mode profiles of the SFG light at 25°C, described by the y-component of the electric field, where the arrows indicate directions of the electric field; (c) effective indices for the TM modes of the SFG light, as the functions of the waveguide temperature; (d–f) theoretical conversion efficiencies (CEs) by coupling among TM00, TM01, TM10, and TM11 modes of the high-intensity pump and signal lights for the SFG lights with (d) TM00, (e) TM01, and (f) TM10 modes, respectively; (g) predicted temperature conditions for producing the TM00 (F00, cyan area), TM10 (F10, red area), and TM01(F01, blue area) modes of the SFG light by comparing the maximum CE.
