The invention provides an optical system for use in a stable, temperature- insensitive birefringent crystal interferometer (BCI). The optical system includes a first block of light transmissive birefringent material having an input port and an output port, the material having in the spectral region of desired device operation a net retardance at a first temperature, and straining means for inducing a strain in one of the first block and a second block of light transmissive material optically coupled to the first block, the strain induced for maintaining the net retardance substantially unchanged from the net retardance at at least a second other temperature. Advantageously, the optical system uses a single variety of crystal, which is cheaper, more robust, and has better performance than BCIs having two crystal varieties.
