Abstract

A high performance HDWDM multiplexer capable of combining 32 channels spaced 1 nm apart onto a monomode fiber is reported. A microlens array is utilized to give a channel bandwidth of 0.7 nm. The wavelength range is 1.5285 micrometers to 1.5595 micrometers , within the erbium fiber amplification range. The mean insertion loss over 32 channels is 6.7 dB, and the polarization sensitivity is less than 0.7 dB. A design for a more compact and lower loss device is also presented.
