We study the phenomenon of controlling the light by light known as the optical bistability for the two-dimensional tilted Dirac system. Using the Boltzmann approach under relaxation time approximation, we find that the optical bistability can be controlled by the nonlinear response of the system. For the prototype, we consider an inversion symmetry broken system. We find that the optical bistability associated with the nonlinear response is tunable with the strength of the tilt, gap and chemical potential. The resulting features suggest the inputs for the development of future-generation optical devices.

二维倾斜狄拉克系统的可调谐光学双稳态

我们研究了二维倾斜狄拉克系统的光学双稳态现象，即光控制光的现象。利用弛豫时间近似下的玻尔兹曼方法，我们发现光学双稳态可以通过系统的非线性响应来控制。对于原型，我们考虑反演对称破缺系统。我们发现与非线性响应相关的光学双稳定性可以通过倾斜、间隙和化学势的强度来调节。由此产生的特征为下一代光学设备的开发提供了输入。
