We experimentally investigate the effects of optical injection attacks on the transmitter side of QKD systems. Previous studies have primarily considered such attacks in the context of optical injection locking with slight frequency detuning between the master (Eve) and slave (Alice) lasers. Here, we demonstrate the impact of these attacks over a broad spectral range λ = 1275 − 1650 nm, showing a reduction in the relative key length under the decoy-state BB84 protocol.
