Abstract

Optical signal receiver is a crucial element in Free Space Optical Communication (FSOC) system. Single-Mode Fiber (SMF) is commonly utilized in receivers for connecting with the subsequent optical fiber communication devices. However, the conventional SMF’s tiny core size and the random drift of the signal laser’s optical axis cause small field of view, and the optical signal acquisition and coupling issues was limited. Herein, a wide field of view optical signal receiver via pump and signal combiner was proposed and demonstrated. The experimental results show that the detection field of view of the pump and signal combiner with a 20/400 μm double-clad fiber increased about 40 times, compared with using a 6/125 μm SMF. Additionally, with the home-build adaptive fiber tip controller, the wide detection field of view can further improve the stability of optical signal receiving in the dynamic optical signal receiving system.
