A torsional micro-electro-mechanical systems (MEMS) mirror module provides for thermally-stable ancillary modes of mirror oscillation (e.g., vertical, horizontal, and rocking) by utilizing MEMS die packaging techniques that implement a cantilevered (i.e., fixed-free) die package in which one end of the die is partially fixedly-attached to a die carrier substrate while the non-attached end of the die is free from the die carrier substrate and unsupported. The cantilevered die package with fixed-free architecture effectively decouples the effects of coefficient of thermal expansion (CTE) mismatch of the MEMS die, die-bond adhesive, and die carrier substrate on temperature-dependent MEMS flexure stress. Ancillary mode oscillation frequencies changes with temperatures are thus limited to a smaller range relative to those experienced with conventional package designs.
