The optical design of a photonic switching system is described in deta
il. The system is a 4-f imaging system with one lens design based on a
Petzval lens and the second lens design based on a double Gauss lens.
The assembled system is 60 mm x 70 mm x 370 mm and features a single
imaging Stage, pupil division for beam combination, and a single fiber
bundle for both input and output. A brief description of the system r
equirements is provided, and the implication of some of these requirem
ents for the paraxial design is explained. The choice of design forms
for the lenses is explained, the design process is outlined, and the f
inal lens designs are provided. Lens tolerancing is outlined and the f
inal lens tolerances are provided. Finally, the assembly and the align
ment processes are described. (C) 1997 Optical Society of America.
