Abstract
Two Vertical Cavity Surface Emitting Laser (VCSEL) diode structures based on InGaAs-GaAs and GaAs-AlGaAs are considered for thermal analysis and their impact on 850 nm digital optical link are investigated. The effect of Multi Mode Fiber (MMF) link length and VCSEL temperature on the overall link performance is compared for both the cases under 1.25 Gb/s transmissions. Bit Error Rate (BER) of 2.02 × 10−5, 1.48 × 10−5 and 2.15 × 10−5, 1.55 × 10−5 for InGaAs-GaAs based VCSEL and GaAs-AlGaAs based VCSEL at 25°C and 40°C are predicted at a fiber length of 1 km. Optimum biasing conditions pertaining to maximum 3 dB bandwidth for both the structures are also determined.
