IdealPhotonics' 1300-1500nm SLD diode, based on the InGaAsP/InP material system, is a low-coherence light source. Utilizing a multimode interference waveguide and quantum well hybrid technology, it achieves an ultra-wide spectrum of 80-200nm and an output power of 20-80mW. In applications such as 1310nm optical coherence tomography (OCT), 1450nm tissue moisture detection, and 1550nm fiber optic sensing, it exhibits <85% polarization accuracy and -140dB/Hz low noise characteristics. Its innovative "spectral groove suppression" technology improves the side-mode suppression ratio to 35dB, making it a core light source solution for mid-infrared biomedical detection and industrial measurement.Employing an InGaAsP/InP multi-quantum-well and multimode interference waveguide structure, a revolutionary combination of a record-breaking spectral width of 100-250nm and a power output of 40-100mW is achieved. In three high-end medical and industrial applications—1310nm cardiovascular OCT (4μm resolution), 1450nm skin moisture quantification (0.1% accuracy), and 1550nm pipeline corrosion detection—its innovative "adaptive spectral filtering" technology improves the side-mode suppression ratio to 40dB while maintaining an ultra-low relative intensity noise of -138dB/Hz, redefining the performance benchmark of mid-infrared broadband light sources in cross-domain precision measurements.
