The compact, low-cost, and reliable light source with extreme broadband emission demonstrates significant potentials for spectroscopic and commercial OCT applications requiring ultrahigh spatial resolution. © FAMS, Inc.Nonidentical multiple quantum well; Optical coherence tomography (OCT); Spectroscopic OCT; Superluminescent diode; Ultra-high resolution OCTBandwidth; Semiconductor diodes; Spectroscopic analysis; Tomography; Nonidentical multiple quantum well; Optical coherence tomography (OCT); Spectroscopic OCT; Superluminescent diode; Ultra-high resolution OCT; Optical properties; article; diode; image quality; imaging; light; optical coherence tomography; priority journal; spectral sensitivity; spectroscopy; Semiconductor Devicesjournal article2-s2.0-32344445138
