Abstract

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 dual-mode 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. The phase noise of the RF output is measured by using the down-conversion method. 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.
