Wavelength and Mode-Spacing Tunable Dual-Mode Distributed Bragg Reflector Laser
2013
IEEE Photonics Technology Letters
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.
