Abstract :
The materials and processes for fabricating a compact multiple-element slab waveguide spectrograph suitable for multimode fiber-optic wavelength-division-multiplexing (WDM) applications are described. A fabrication scheme based on thick-film solder glass glazing, hot-press lamination and optical finishing was chosen to produce a precisely dimensioned glass-ceramic spectrograph blank structure that is compatible with grating replication manufacturing technology and suitable for hermetic packaging. The laminated blank consists of alternating layers of glass-ceramic spacer plates and optical glass wafers bonded together with a screen-printed solder glass adhesive. The exact interlayer optomechanical registration, achieved in the laminated spectrograph blank was essential for obtaining spectral referencing functionality and a passive alignment packaging scheme. A spectrograph optical subassembly package was developed and implemented as part of a multichannel spectrum analyzer receiver in a prototype optical WDM sensor interface system
