Abstract :
Optical labeling via frequency-shift keying (FSK) modulation capability of a grating-assisted codirectional coupler with sampled grating reflector laser is investigated for the first time. FSK modulation can be best implemented with only the phase section current and optical frequency deviation of 20 GHz is achieved. The measured frequency modulation response indicates the limitation of the maximum modulation rate is sufficient for Internet protocol packet optical labeling.
