Abstract
Until recently, single mode couplers were laboratory curiosities. Now, however, several companies offer high quality couplers as commercial products. Improvements in coupler manufacturing have been made, on a regular basis, to the point where 50% couplers with less than 0.5 dB loss are routinely available. Generally, these couplers are fabricated by hand, a, process which is inefficient, in terms of the consistency of the couplers fabricated and extremely labor intensive, thereby limiting total output. In this paper, we discuss an automated single mode coupler facility. This assembly system has the advantages of high yield, reproducible coupling ratio and loss values, and high volume output.© (1986) COPYRIGHT SPIE--The International Society for Optical Engineering.
