Abstract
Official abstract text for this publication.
A three-terminal VCSEL is provided that has a reduced fall time that allows the VCSEL to be operated at higher speeds. Methods of operating the three-terminal VCSEL are also provided. The VCSEL can be operated at higher speeds without decreasing the optical output of the VCSEL when its in the logical HIGH state.
First claim
Opening claim text (preview).
What is claimed is: 1. A three-terminal vertical cavity surface emitting laser (VCSEL) comprising: a substrate having at least a top surface and a bottom surface; an emitter contact corresponding to a first terminal; a first plurality of n-type layers disposed on top of the top surface of the substrate, wherein the first plurality of n-type layers comprise pairs of layers of alternating high and low refractive index that operate as a first distributed Bragg reflector (DBR);…
