This paper presents a new flow-coating method to fabricate adhesively bonded optical fiber coupler for acoustic signals. The goal is to decrease losses as acoustic signals representing Lamb waves are transferred from one fiber to another. The flow-coating method significantly improves the geometry of the adhesive in the coupler. As a result, the losses to the acoustic signal energy are significantly reduced in the coupler.
