Abstract
An optical emitter includes a vertical cavity surface emitting laser (VCSEL), an equalization circuit coupled to the VCSEL; and a current source coupled to the VCSEL and the equalization circuit. The equalization circuit is configured to divert a first current from the current source to the VCSEL at a first data frequency and divert a second current greater than the first current from the current source to the VCSEL at a second data frequency higher than the first data frequency.
