Abstract
A 5-Gb/s data modulation and transmission is investigated using Fabry-Pérot InGaAs quantum-dot lasers emitting at approximately 1.3 μm. Error-free transmission of 5-Gb/s data at room temperature over 4 km of single-mode fiber (SMF) and over 500 m of installed grade multimode fiber are demonstrated for the first time. The temperature dependence of the data modulation performance is also studied. We report error-free 2.5-Gb/s data modulation up to 50°C and transmission over 4 km of SMF with a Q-factor penalty of 0.5 dB. Error-free 5-Gb/s data modulation is observed up to 30°C and 5-Gb/s data transmission over 4 km of SMF with a Q-factor penalty of 0.8 dB is obtained at 40°C. The lack of overshoot and ringing in the eye diagrams is attributed to the large damping factor observed under small-signal modulation.
