Abstract
Active relative intensity noise mitigation in nested interferometers using trans-impedance amplifiers is provided by splitting an optical carrier signal into a first version and a second version, wherein the first version is orthogonal to the second version; re-combining predefined portions of the first version and the second version to determine a noise level; modulating at least one of the first version and the second version based on the noise level to reduce the noise level; after modulating the at least one of the first version and the second version based on the noise level, encoding data onto at least one of the first version and the second version; and recombining the first version and the second version to transmit the data.
