We propose mode-locked laser diodes (MLLDs) for their deployment in a low-cost and portable optical coherence tomography (OCT) system. OCT is an essential imaging technique used for medical diagnoses in dermatology, ophthalmology, and cardiology. Based on low-coherence interferometry, OCT directs infrared light through various layers of tissue, which is reflected onto a detector and resolved as an image. Generally, swept-source OCT (SS-OCT) systems perform better than grating based systems and time domain OCT but …

We present a theoretical overview and a proposed methodology which demonstrates SLASOPS (single laser asynchronous optical sampling) as a single-laser alternative to the conventional two-laser ASOPS technique. We propose the optical and electronic setup in which SLASOPS may be achieved experimentally with a single 2-section mode-locked laser diode as the pulsed-laser source and simulate how asynchronous optical sampling is generated and detected theoretically. We highlight the technique’s ability to provide custom…
