An integrated or monolithic photonic circuit that modulates RF signals onto optical signals and then performs a channelizing filter function according to the RF content. According to an exemplary embodiment, the photonic circuit is employed in an aircraft system that includes a front end, a photonic circuit, an optical connection, and an electronic module at some distant location in the aircraft. RF signals are received by an antenna in the front end, the RF signals are then modulated onto optical signals by a modulator and a laser, the modulated optical signals are filtered by a filter array according to a channelizing filter function, and the modulated and channelized optical signals are then carried over the optical connection to the electronic module. Other options like a wavelength-tunable laser and corresponding feedback feature, as well as ring filters with integrated semiconductor optical amplifiers (SOAs) are also possible.
