Abstract

Modeling the effects of stress birefringence is critical for polarization sensitive optical systems. Optical design and optomechanical software tools to model stress birefringence are discussed and illustrated for three examples. The first example compares retardance in calcium fluoride lenses as a function of shape. The second example discusses the modeling of a beam splitter in an LCD projector. Lastly, stress birefringence modeling tools are demonstrated in detail in the design of focusing and collimating lenses for a WDM wavelength selective switch. The wavelength selective switch, operating over the telecom C-band (1530-1561nm), employs a liquid crystal polarization modulator to select the output fiber for each input channel. Over the operational temperature range, CTE mismatches between the glasses and mounting materials induce stress in the optical elements creating cross-talk between the output optical fibers. Cross-talk is computed as a function of temperature for several potential design concepts.
