Abstract

A GaInAsP DFB laser modulated with a 50 Mbit/s pseudorandom AMI FSK signal was locked to the 2p₁₀−3d₅ transition of argon at 1.2960μm using the optogalvanic effect. No significant degradation in frequency stability due to the modulation was observed. When the signal was demodulated, the power penalty due to the frequency-locking servo loop was found to be less than ⅓dB.
