  • Patent number: 11955778
    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.

  • Publication number: 20220239056
    Abstract: A method and system for analyzing Vertical-Cavity Surface-Emitting Lasers (VCSELs) on a wafer are provided. An illustrative method of is provided that includes: applying a stimulus to each of the plurality of VCSELs on the wafer; measuring, for each of the plurality of VCSELs, two or more VCSEL parameters responsive to the stimulus; correlating the measured two or more VCSEL parameters to define a value of a common performance characteristic; and identifying clusters of VCSELs having similar values of the common performance characteristic. The clusters of VCSELs may be determined to collectively meet or not meet an optical performance requirement defined for the VCSELs on the wafer.

  • Patent number: 9948386
    Abstract: An optoelectronic configuration method is provided. The method includes determining a baseline link budget value for the VCSEL. The method applies a constant input value to a VCSEL and monitors the output of the VCSEL. The method calculates a first link budget value from the inputs and outputs of the VCSEL and compares the first link budget value with the baseline link budget value to determine either a pass state of the VCSEL or a fail state of the VCSEL. If a fail state of the VCSEL is determined, the method may iteratively apply modified inputs to the VCSEL until the desired relationship between the first link budget value and the baseline link budget value is obtained.
