High speed, ultralow noise, tensile strained InGaAlAsMQWlasers emitting at 1300 nm for optical communication andmicrowave applications

Abstract
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.
