20 GHz Bandwidth High Dynamic Range 1.3 μm Buried Heterostructure Laser Modules

A 20 GHz bandwidth 1.3 μ InGaAsP/InP Straight-Wall Mass-transport Buried Heterostructure laser diode was developed to operate in a microwave fiber optic link. When used in a microwave link, the laser has a typical RF insertion loss of 37 dB, an equivalent input noise density less than -115 dBm/Hz, a 1 dB compression dynamic range greater than 138 dB.Hz and a spurious signal free dynamic range of 97 dB.Hz 2/3 . The wide bandwidth, high dynamic range and low-noise of the laser module were obtained through the design of the package, the subcarrier and the laser chip
