Micromachined low-finesse Fabry-Perot interferometer for the measurement of DC and AC electrical currents

A micromachined low finesse Fabry-Perot interferometer for measuring DC and AC electrical current is presented. Interrogation of the microcavity is achieved by a dual-wavelength fiber Bragg grating technique working in quadrature. A linear relation between the DC electrical current and the optical p...
