Here, we describe the use of multimode fiber-coupled light-emitting diodes (LEDs) as a simple, low-cost alternative to more conventional light sources, and demonstrate their capabilities by extracting the main figures of merit of optoelectronic devices based on monolayer MoS 2 .

Thorlabs' light-emitting diodes (LEDs) are pigtailed with multimode (MM) fiber and are available at visible or NIR spectral ranges with center wavelengths from 470 nm to 810 nm. optical. Discover our range of Fiber Coupled LEDs, available in UV, Visible, and NIR versions, covering wavelengths from 375nm to 1550nm. We also offer multi-wavelength. Optoelectronic device characterization requires to probe the electrical transport changes upon illumination with light of different incident powers, wavelengths, and modulation frequencies. This task is typically performed using laser-based or lamp + monochromator-based light sources, that result. The Fiber Coupled Broadband LED Light Source utilizes a VIS/NIR phosphor converter to convert the output of a 450nm LED chip into a broad 420 – 900nm spectrum. This light source provides highly efficient coupling with SMA connected multimode fibers with diameters of 50µm to 1mm and a numerical. Mightex WFC-series multi-wavelength fiber-coupled light sources are enabled by the latest LED technologies, and Mightex's proprietary beam combining and coupling optics. Up to eight (8) LEDs are coherently combined into a single multi-mode fiber with the highest efficiency practically possible.
