Oblique Wedge Lensed Fibers

Oblique Wedge Lensed Fibers
	Product Features	Product Applications
	The traditional wedge fiber lens needs to be coated with antireflective coating on the end surface to minimize the light reflectivity, while the oblique wedge lensed fiber, due to its special geometry, makes the refractive angle between the cylindrical lens and the laser chip without affecting the optical path transmission, which effectively avoids the impact of reflected light on the life of the laser chip, and also eliminates the signal noise caused by reflected light. Compared with the traditional process, it reduces the cost problem caused by the low yield of coating and the long-term reliability problem caused by the coating process.	Assembly for LD
		Optical direct coupling from LD chip into fiber
		Optical direct coupling from fiber into waveguide
