A steady sweep
For swept source optical coherence tomography and high-speed transient spectroscopy, micro-electromechanical-systems-based vertical-cavity surface-emitting lasers (MEMS-VCSELs) are an appealing optical source owing to their narrow linewidth, continuous single-mode tuning and high-speed tunability. In particular, a wide tuning range (>100 nm) near 1,310 nm would be extremely
