Power-efficient high-speed driver for a vertical-cavity surface-emitting laser

摘要

An optical transmitter is disclosed. In accordance with some embodiments of the present disclosure, an optical transmitter may comprise a vertical-cavity surface-emitting laser (VCSEL) and a VCSEL driver. The VCSEL driver may comprise an input stage configured to receive a voltage signal and a low-impedance output stage comprising an input coupled to the input stage and a low-impedance output coupled to the VCSEL and configured to provide a modulated output current to the VCSEL.
