摘要：
A high-speed distributed feedback laser based on the reconstruction equivalent chirp technology has been proposed and demonstrated. Due to the enhanced detuned loading and the photon-photon resonance effect, the 3-dB modulation bandwidth is improved to 29 GHz. Utilizing the proposed method, the relative intensity noise is reduced to below -156.37 dB/Hz, and the frequency chirp is decreased from 4.74 to 2.58. Moreover, the modulation maintains excellent linearity, with a 1-dB compression point of more than 18 dBm.
