Tiny Tip Couples Diode Laser to Single-Mode Fiber
Nov 1, 2004 — The inefficient coupling of a diode laser's power into a single-mode fiber has been a major stumbling block in modern fiber optic telecommunications systems. These coupling losses are one of the motivations for the development of fiber lasers as telecommunications transmitters because fiber-to-fiber can be less lossy than semiconductor-to-fiber coupling. When a diode laser is coupled to a fiber, a microlens is usually placed between the two to maximize the coupling efficiency, and many...
