2120700 9307519 PCTABS00021 A package for an IOC fabricated from an anisotropic material, such as X-cut lithium niobate or lithium tantalate, having identical thermal expansion coefficients in the X and Y directions and a different thermal expansion in the Z direction, or for an IOC fabricated from an isotropic material, such as gallium arsenide or silicon, includes an IOC enclosure having a planar mounting surface which has identical thermal expansion coefficients in the X and Y directions. The coefficients of the planar mounting surface are relatively similar to the thermal expansion coefficients of a planar surface of the IOC. A planar surface of the IOC is attached to the planar mounting surface of the package.
