| Summary: | In order to better understand the damage phenomenon and failure mechanism of planar lightwave circuit (PLC) optical splitters under force cycling, this paper established an online test experimental platform to study their optical and mechanical performance response under the action of force cycling. The research results show that under the action of force cyclic loading, the weakest area in the PLC optical splitter is the eight-channels output fiber array–PLC chip adhesively bonded joint; the moments of force cycle loading and unloading cause the insertion loss (<i>IL</i>) of the PLC optical splitter to fluctuate suddenly, especially at the moment of unloading. In addition, the research results show that under the action of force cyclic loading, the local deformation and damage behavior of the weak area can be reflected by the optical performance parameter indicators monitored in real time. This study helps to identify the location of weak areas of PLC optical splitters and understand their response behavior under force cyclic loads, which can provide a useful reference for subsequent measures to improve their long-term reliability. |
