A 5-Port Photonic Lantern for Light Beam Combining

Abstract:

We demonstrate a 5 port photonic lantern for light beam combining. This is a potential key component for low-cost wideband light source. The photonic lantern is a fused-taper fiber device with 5 energy delivery optical fibers into a multi-mode fiber. The input fibers have Ge-doped core diameter of 110μm and the output multimode fiber has a core diameter of 30μm. In the tapered section light in different fibers couples with each other and the multimode fiber terminal output all wavelengths of the light from 5 LED sources which be used to test the device. Different broadband sources can be obtained by using photonic lantern and different combination of LED sources. This paper shows the feasibility of using the photonic lantern to obtain wide-band light source by narrow bandwidth light sources.
