Abstract
A method and system for large scale Vertical-Cavity Surface-Emitting Laser (VCSEL) binning from wafers to be compatible with a Clock-Data Recovery Unit (CDRU) and/or a VCSEL driver are provided. An illustrative method of binning is provided that includes: for at least a portion of VCSELs on a wafer, measuring a set of representative parameters of the VCSELs, of predetermined DC or small-signal values, and sorting the measured VCSELs into clusters according to the measured set of representative parameters of the VCSELs; further sorting the clusters into sub-groups that comply with specifications of the VCSEL driver; and providing a feedback signal to the CDRU for equalizing control signals provided to the VCSEL driver.
