Tensile strained InGaAlAs multiquantum well lasers emitting at 1300 nm have been developed by using a ridge waveguide structure. The lasers demonstrate >20 GHz modulation bandwidth and very low relative intensity noise of –150 dBm/Hz. 10 dB improvement in optical link loss has been observed compared to previously reported results for microwave lasers in the InGaAsP system.
