Abstract :
A high-speed ridge waveguide laser with undoped strained MQW active region was fabricated and characterized. The lasers demonstrated typical threshold currents of ~20 mA. The electrical impedance of the laser demonstrates -3 dB bandwidths >34 GHz at high bias currents, indicating that the parasitics in our devices are very small. The best laser demonstrated a -3 dB modulation bandwidth of 20 GHz. This is the highest bandwidth achieved for a ridge waveguide laser operating at 1.55 μm
