Paper Abstract

A tree configuration single-mode fiber wavelength division multiplexer (WDM) is proposed and demonstrated. This configuration is similar to tree topology single-mode star couplers which have been reported. Both theoretical analysis and experimental data show that a tree WDM can easily achieve a very high wavelength isolation over a wide wavelength range aroun 1300 nm and 1520 nm. The wavelength isolations measured in our experiment are greater than 28 dB both from 1255 nm to 1335 nm (80 nm-wide range, 41 dB at 1305 nm) and from 1490 nm to 1565 nm (75 nm-wide range). The insertion losses are 0.7 dB at 1300 nm and 1.1 dB at 1550 nm.
