(a) Dispersion of the real part of the fundamental trench-CPP mode effective index with trench depth for different dielectric inserts inside the trench (𝑛=3, 2, 1.44). (b) Dispersion of the imaginary part of the fundamental trench-CPP mode effective index with trench depth for different dielectric inserts inside the trench (𝑛=3, 2, 1.44).
