Description
Dark photons, which can kinetically mix with ordinary photons, represent
the simplest extension to the standard model. Detecting their
oscillations with visible photons could provide crucial insights into
the nature of dark matter and fundamental interactions beyond the standard
model. We propose a novel laboratory-based approach to detect dark photon
oscillations using a laser in an
Optical Time-domain Relectometry (OTDR) setup. The laser light
propagating through the optical fiber undergoes oscillations with the dark
photon, leading to measurable changes in the power flow. These oscillations can precisely measured, leveraging its high sensitivity and efficiency in detecting
small variations in the optical signal. This approach could provide a new avenue for probing dark photon
oscillations in the laboratory and greatly improve the current
experimental sensitivity to dark photon in a wide mass range.
