Abstract

An analysis has been made of several bi-directional coupling schemes that allow duplex transmission over a single optical fiber through the use of wavelength separation. Three basic generic types of couplers have been considered: prism, grating, and dichroic mirror. Included in the analysis is a detailed comparison with respect to throughput loss, internal crosstalk and external crosstalk rejection of two potential implementations of each generic type. The throughput loss calculation includes the effect of scattering and absorption from component surfaces and volumes, and an approximate calculation of losses due to basic diffraction limitations. A detailed crosstalk analysis based on the estimated scattering mainly from component surfaces has also been performed.
