The photon lifetime is modified by decreasing the top mirror reflectivity either by shallow-surface etching or by Bragg-reflector layer-pair removal. Significant improvements in both static and dynamic VCSEL performance as well as the extraction of internal VCSEL device parameters are achieved.Dampinghigh speedmodulationphoton lifetimevertical-cavity surface-emitting lasers (VCSEL)Effect of Cavity Lifetime Variation on the Static and Dynamic Properties of 1.3-μm Wafer-Fused VCSELstext::journal::journal article::research article
