We have formulated and analyzed a model of in‐plane self‐sustained pattern formation in a quantum well heterostructure under bistable electro‐optical absorption. We have found a number of patterns which contain regions (quasi‐neutral or charged) with different spreading of the electron and hole wave functions and different densities of the two‐dimensional (2D) electron–hole plasma. Lateral redistributions of the plasma induce a complex (two‐ or three‐dimensional) configuration of the electrostatic potential. Stationary, moving, quasi‐neutral, and charged patterns are studied.
