Abstract

A gain-flattening filter (GFF) for minimum manufacturing errors (12 designs submitted) and dense wavelength-division multiplex (DWDM) filters for low group-delay (GD) variation (9 designs submitted) was the subject of a design contest held in conjunction with the Optical Interference Coatings 2001 topical meeting of the Optical Society of America. Results of the contest are given and evaluated. It turned out that the parameter space for GFFs with optimum performance when manufacturing errors are not considered is much different from that when manufacturing errors are considered. DWDM filter solutions with low GD variation are possible.

Thelen, Design of Optical Interference Coating (McGraw-Hill, New York, 1989), Table 10.1, p. 208. This design does not meet the specification of Table 1 for Δλ-3.0 dB (50%) because of an error: The last two layers had thicknesses 0.75075H and 0.48694L instead of the values published in the contest announcement and this paper. Changing the numbers of the last two layers brings the design into specification but increases the variation of GD from 10.5 to 12.7 ps.
