HgTe and zero-gap HgCdTe have record, picosecond speed, optical nonlinearities at 10.6μ. They are caused by carrier temperature modulation, which produces large carrier density variations in zero-gap materials. The thermal process is only beginning to saturate at 1 MW/cm2; at that intensity , the dielectric constant of HgTe is modulated by about 10%. Further enhancement of these nonlinearities may be achieved with suitable doping or alloying.
