Abstract
The dynamic characteristics are investigated for an 8-μm-radius directional-emission microdisk laser subject to optical injection. Single mode operation with lasing mode wavelength of 1540.1 nm and the side mode suppression ratio of 35 dB is realized for the microdisk laser at the biasing current of 10 mA and the temperature of 288 K. Under the optical injection from a tunable laser, optical injection locking and the enhancement of the 3dB bandwidth of small signal modulation response from 3.4 to 13.7 GHz are observed for the microdisk laser biased at 7 mA with an injected optical power of 0.5 mW. By varying the wavelength detuning between the injection light and the lasing mode, we demonstrate the nonlinear states of four-wave mixing, period-one and period-two oscillations from the lasing spectra. Multiple peaks are observed for the period-one and period-two oscillation states.
