Abstract
Until now, all local light injectors used single very small radius macrobends (1-4 mm) to launch power into fiber cores. This results in very high stresses–10-4 times the fiber proof-test level, respectively. Furthermore, injected power is low, approximately –45 dBm, and is usually not at the system operating wavelength. In contrast, small scale, ~1/10-μm amplitude, fiber-axis distortions of the correct periodicity create resonant power coupling between cladding and core power that is more than 100 times greater than macrobend techniques while inducing fiber stresses well below proof-test values. Here results and design details for this injector are described.
