Butterfly Laser
A butterfly-package laser is a highly integrated, hermetically sealed metal-package semiconductor laser module using a standard14-pin butterfly housing. It incorporates a TEC thermoelectric cooler, NTC thermistor, and back-facet monitoring PD; some designs include an optical isolator and support fiber-pigtail output. A wide choice of wavelengths, high coupling efficiency, good stability, and excellent beam quality make it a stable continuous source for pump coupling, fiber sensing, spectroscopy, and optical test systems. Fujin Optoelectronics provides integrated fiber polishing, end-face AR coating, and pigtail connector assembly, reducing end-face reflection and back-reflection interference in the output path and improving long-term system stability.

VCSEL, short for Vertical Cavity Surface Emitting Laser, is a widely used semiconductor laser component in modern optoelectronics. Unlike traditional edge-emitting lasers, VCSEL emits laser light vertically from its chip surface. Thanks to its low power consumption, stable beam quality, low cost, and easy integration, it has become the core light source for 3D sensing, wearable devices, and high-speed optical communication.
