Design and Fabrication of 1 × 2 Nanophotonic Switch

Figure 4

Fabricated “Y coupler.” (a) Top view microscopic image of the overall fabricated device. (b) Enlarged image shows the input waveguide which splits into a pair of waveguides; (c) and (d) show SEM images of the lower and upper encompass areas (shown in Figure 4(b)) that define the coupling of light from fiber to the silicon waveguide and the fabrication of the T-junction itself, respectively. (e) Placing the particle in the slit (the particle is marked with white arrow). Left part is an upper view of the particle and the right part is the 3D mesh.
