Your library or personal account may give you access

Abstract

we report a 1.3μm 30-GHz directly modulation distributed feed-back laser with narrow linewidth of 130kHz and high side-mode suppression ratio of 52dB. The output power is more than 16mW at 100mA and the input 1-dB compression point is showed with different frequencies.
