Source: Nature The Fabry–Pérot Interferometer: An Overview Operation Principle A Fabry–Pérot interferometer consists of two highly reflective mirrors with some transmissivity, forming a resonator with sharp resonances in transmission. In resonance, the input and circulating waves constructively interfere, leading to minimal reflection. In anti-resonance, most radiation is reflected. Frequency-Dependent Transmittance The resonance frequencies can be
