On-chip terahertz biosensing with topological Mach–Zehnder interferometer

Terahertz photonic sensing provides a powerful platform for probing biological materials on-chip due to its strong sensitivity to molecular resonances. Here, we demonstrate a complementary metal-oxide-semiconductor-compatible, silicon-based topological Mach–Zehnder interferometer operating in the THz regime for robust...
