In recent years, widely tunable micro-electro-mechanical systems vertical cavity surface-emitting lasers (MEMS-VCSELs) have found commercial application in swept source optical coherence tomography medical imaging and also show considerable promise in metrology and spectroscopy. These devices exhibit fractional tuning ranges of >11% of the center wavelength, wavelength tuning repetition rates over full tuning range of >1MHz, and clean single-mode operation. These properties, in conjunction with small size and wafer scale fabrication and testing, promise an economical optical source that can impact sensing applications from the visible to the mid-infrared.
