摘要：

We propose a novel approach to dual-channel optoelectronic oscillators (OEOs) with enhanced frequency band by leveraging directly modulated (DM) semiconductor lasers under optical injection. In this configuration, the frequency-tuned optical signal from a master laser is introduced into a single-mode slave laser, facilitating multioptical-mode operation. The resulting multiple optical frequencies emitted by the slave laser facilitates a DM-OEO signal at a frequency exceeding the laser's intrinsic modulation bandwidth. Through the deployment of a dual-channel OEO based on the DM multimode laser signal, stable oscillation signals have been successfully achieved simultaneously at 15 and 18 GHz with phase noise levels of 96.43 and 95.62 dBc/Hz, respectively, at a 10-kHz offset frequency.
