Claim 0:
1. A method for large scale Vertical-Cavity Surface-Emitting Laser (VCSEL) binning, comprising:
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;
matching between an input impedance and an output impedance of the VCSELs and a VCSEL driver;
further sorting the clusters into sub-groups based on the matching to that comply with specifications of the VCSEL driver; and
providing a feedback signal to a Clock Data Recovery Unit (CDRU) for equalizing control signals provided to the VCSEL driver.
