Small mirrors and long pass filters

If very small mirrors or long pass filters with dimensions of only a few millimeters are needed then such devices on single crystalline GaAs substrates can be used. Single crystalline GaAs has a good thermal conductivity of 55 W/(m*K) and can be cutted into small rectangular chips because of its cubic crystal structure.
