Abstract
We briefly review the physics of two-photon absorption processes in low-dimensional systems. The anisotropic selection rules of the multiphoton absorption in quantum wells and quantum wires are exploited to study the 2p-exciton states and the otherwise forbidden transitions among quantized subbands of different quantum numbers.
