Abstract

We report on the progress of a volume manufacturable oxide-confined 850-nm vertical-cavity surface-emitting laser (VCSEL) operating at 25 (NRZ) to 56 (28 GBd PAM-4) Gbit/s data rate from room temperature (RT, 25 °C) to 105 °C. Our devices offer clear eye openings over a wide-temperature range without applying equalization or forward error correction (FEC) at either transmitter or receiver sides. Even at extreme operating temperatures, the meticulously optimized devices offer ameliorated dynamics characteristics without the need for these additional power-hungry signalprocessing techniques. The equalization-free characteristic reduces the reliance on signal compensating circuits in the transceiver modules with the flexibility of operating over a wide temperature range for short-teach high-speed optical interconnects and automotive applications.
