Paper Abstract

The widespread use of fiber optic couplers has been significantly inhibited by their high cost. This paper presents a review of three generic types of fiber optic couplers, concentrating on their manufacturability. It is this ease of manufacture that ultimately determines the coupler cost and availability in large quantity. Fused biconical taper couplers prove to be quite versatile with excellent optical characteristics but less adaptable to mass production. A detector/tap coupler is described that has much improved manufacturability and includes a detector in the coupler itself, thereby saving connector costs. Finally, an active bidirectional coupler is discussed that incorporates a source and detector in the coupler body, thereby eliminating the need for all external device connections. This compact and rugged device is easily manufactured in large quantity while at the same time having excellent optical characteristics.
