Abstract

Reconfigurable testing of a high-speed optical link based upon on-wafer probing of an oxide-confined 850 nm vertical-cavity surface-emitting laser (VCSEL) and a GaAs P-i-N photodetector (PD) is demonstrated at a non-return to zero (NRZ) modulated data rate up to 50 Gb/s at room temperature and 43 Gb/s at 85℃ over back-to-back distance. Without any impedance matching network, trans-impedance amplifier, or equalization technique present at the received side, the optical link has not only shown robustness but also achieved outstanding signal-to-noise ratios (SNRs) over the operating temperature range.
