Abstract
Electronic predistortion of distributed-feedback (DFB) lasers is usually required for meeting analog-system performance requirements. To determine the characteristics that make a laser predistortable, we have evaluated about 100 DFB lasers from several manufacturers by using a number of diagnostic tests. These tests included optical spectrum, optical backreflection, L/I, dL/dI, dV/dI. FM response, and second-order two-tone intermodulation (IMD2) response. Although each lest provides insight into one or more aspects of laser linearity performance, IMD2 has proven to be the most useful diagnostic test.
