Paper Abstract

A variety of ball-lens based optical add/drop multiplexers (OADMs) are designed and implemented. Insertion losses as low as 0.5 to 0.6 dB for the reflection light-path, and 1.2 to 1.5 dB for the transmission light-path are demonstrated. The 0.5-dB passband and -30 dB stopband for 100-GHz OADM are 0.35 nm and 1.15 nm, respectively. The reflection path has an isolation 15 dB. In addition to the distinct cost advantage of ball lenses over the GRIN lenses, the ball-lens based OADMs also offer a significant simplification in packaging due to the intrinsic spherical symmetry of ball lenses. Optical designs and optics-related packaging issues are discussed in detail.
