    Akinetic all-semiconductor swept lasers boost OCT image quality

    Optical coherence tomography (OCT) image quality continues to improve thanks to advances in detection systems and improved light sources such as wavelength-tunable vertical-cavity surface-emitting lasers (VCSELs) . But a different light source that eliminates the mechanical tuning of VCSEL and external-cavity lasers is rapidly gaining momentum, as it could offer superior OCT image quality and potentially lower-cost manufacture: akinetic all-semiconductor swept laser sources from Insight (Lafayette, CO). 1 Nearly all swept-wavelength light sources use mechanical means to move optical filter elements or microelectromechanical systems (MEMS) mirrors to tune the output wavelength; unfortunately, these mechanical elements can exhibit hysteresis, cause cavity instabilities ...
