Design of Refractive Index Sensors Based on Valley Photonic Crystal Mach–Zehnder Interferometer

The refractive index is an important optical property of materials which can be used to understand the composition of materials. Therefore, refractive index sensing plays a vital role in biological diagnosis and therapy, material analysis, (bio)chemical sensing, and environmental monitoring. Convent...
