Design of two-element of 1300nm-1600nm achromatic quarter-waveplate

With the development of laser technology, polarized devices are also more and more widely applied, achromatic wave plate is one of the more polarizing device. Now laser technology requirements achromatic waveplate more, in order to meet this requirement, achromatic waveplate further improve performance and reduce its error small, to obtain a better application.An infrared quarter-wave achromatic retarders in the range of 1300-1600nm has been designed by a combination of the two composite quartz wave plate which is a quarter wave-plate and a half wave-plate. The succinct and simple Jones matrix formalism has been used to derive the general expression for the relationship between the equivalent retardation of the combinations and the wave plate orientation. And then using matlab software to stimulate. The design has advantages of high precision,wide range of wavelength, producing with the same material, saving material, manufacturing of simple features and so on. Whereas the maximum variation does not exceed 0.17%, so it is a good choice for the optical communication. This kind of method to produce high performance combination achromatic quarter-wave plate with other materials also provides a good theoretical basis.
