Abstract:
A method for use in the manufacturing of devices that utilize arrays of optical transmitters comprising the steps of:providing a plurality of said arrays of optical transmitters, including separating said arrays; providing a submount substrate having conductive contacts along a side and having electrical paths to said conductive contacts, said conductive contacts including substantially identical contact patterns in which each contact pattern is configured for connection to one of said arrays; mounting said arrays of optical transmitters to said submount substrate, including electrically linking said arrays to said contact patterns such that each said optical transmitter in each said array is linked to at least one of said electrical paths; performing burn-in processing of said arrays, including: 1) driving each said optical transmitter of each said array by conducting drive signals through said electrical paths of said submount substrate; 2) individually monitoring drive signals for a plurality of said optical transmitters; and 3) selectively adjusting said individually monitored drive signals to approximate preselected burn-in signals for said burn-in processing of said optical transmitters, including varying said individually monitored drive signals for corresponding said optical transmitters on a basis of detecting that said individually monitored drive signals do not approximate said preselected burn-in signals; and after completion of said burn-in processing, dicing said submount substrate to provide individualized said arrays on segments of said submount substrate.
