We propose a novel experimental method for probing light dark matter candidates. show that an electro-optical material’s refractive index is modified in the presence of coherently oscillating background. A high-precision resonant Michelson interferometer can be used to read out this signal. The proposed detection scheme allows exploration uncharted parameter space candidates over wide range masses—including masses exceeding few tens microelectronvolts, which challenging microwave cavity haloscopes.
