A reconfigurable intelligent subsystem may include a bidirectional photonic integrated circuit. The bidirectional photonic integrated circuit may include a distributed reflector (DR) laser or a distributed feedback laser (DFB) that emits light of a first wavelength, and a longitudinal waveguide portion that transmits light of a second wavelength, while attenuating light of the first wavelength. The bidirectional photonic integrated circuit may be coupled to a single mode optical fiber to provide two-way optical communication between a service provider ("headend") and a subscriber.
