Abstract
A tunable photonic channelizer includes an optical signal generator and an optical modulator. The optical modulator receives a first optical signal as an input from the optical signal generator and modulates the first optical signal to create a second optical signal. The tunable photonic channelizer includes an optical filter that is selectively tunable. The optical filter receives the second optical signal, filters the second optical signal, provides a third optical signal as a filtered version of the second optical signal. The tunable photonic channelizer includes a feedback loop between the optical filter and the optical signal generator to provide temperature and/or environmental feedback from the optical filter to the optical signal generator to enable the first optical signal to float in relation to the temperature and/or environmental feedback.
