A record 9 GHz small signal modulation in a single fundamental mode photonic crystal vertical cavity surface emitting laser is demonstrated for the first time. The device is designed by incorporating etched photonic crystal holes in the top distributed Bragg reflector for optical confinement. Emission spectra measured during small signal modulation confirms single fundamental mode operation.
