Antiguided Vertical Cavity Surface Emitting Lasers

摘要

Novel single-mode VCSEL designs based on antiguided structures are discussed. Modal characteristics of single-element, 8-12 μm-dia, ARROW-type VCSELs and two-dimensional phase-locked arrays (4X4 elements) of antiguided VCSELs are studied. ARROW-type VCSELs exhibit low loss for the fundamental mode and strong high-order mode suppression as a result of edge radiation leakage. Preliminary results are ImW single-mode (thermally limited) from 12 μm100mW of single-mode output power with further optimization and efficient heatsinking.
