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.
