In this letter, we report a novel mode-beating distributed Bragg reflector (DBR) laser with dual-mode output. Both the working wavelengths and mode spacing of the dualmode laser can be tuned when the currents injected into the DBR laser are adjusted. The tuning ranges of the laser wavelength and mode-beating frequency are [1527.20 nm, 1531.04 nm] and [91.88 GHz, 94.02 GHz], respectively. A fourth harmonic injection locking is also demonstrated to achieve a synchronized RF output at 93.23 GHz.

A single sideband phase noise of 96.92 dBc/Hz with 1-MHz offset at a down-converted frequency of 13.23 GHz is achieved.
