Abstract
A method of producing a batch of MQW lasers from a plurality of wafers having doping concentrations within a concentration range. The MQW lasers are produced by epitaxially growing an InGaAsP quaternary layer on the substrates in a metal-organic chemical vapor deposition (MOCVD) reactor. The method includes the steps of segregating the substrates into groups based upon the substrate doping concentrations and batch producing the lasers at specific target wavelengths for each segregated substrate group.
