Abstract:
In this letter, we study the effect of many body interactions on the collective response of confined electrons in doped quantum-well (QW) heterostructures to intense far-infrared radiation. Absorption lineshapes are computed both by numerically integrating the equations of motion and by using the appropriately time-averaged equations. For a two-subband double-QW system optical bistability is observed and its parameter range is given. For an asymmetric triple-QW structure driven at /spl omega//spl ap/E/sub 2/-E/sub 0/ Hopf bifurcations occur which generate a strong response at a frequency incommensurate with the drive frequency or any natural frequency of the system.

While obtaining the Ph.D. degree, he developed nonlinear dynamics models in nanotribology and subsequently focused on the nonlinear dynamics of far-infrared-driven intersubband transitions in n-doped semiconductor quantum-well heterostructures. From April 2001 to August 2001, he was a Postdoctoral Fellow at the Physics department at Washington State University. Since August 2001, he has been a Postdoctoral Fellow at the School of Electrical and Computer Engineering at Georgia Institute of Technology. His work currently focuses on models of terahertz sources in semiconductor heterostructures and on optical bistability in far-infrared-driven intersubband transitions in n-doped double quantum wells.
Dr. Batista is a member of the American Physical Society.

D. S. Citrin received the B.A. degree in physics from Williams College, Williamstown, MA and the M.S. and Ph.D. in physics from the University of Illinois, Urbana-Champaign, in 1985, 1987, and 1991, respectively.
He conducted his dissertation on the theory of optical properties of quantum wires and related applications for light modulators and lasers. This work brought to the fore the importance of the interplay of band mixing and structure geometry on the optical properties of quantum wires. Following the Ph.D., he was a post-doctoral fellow at the Max Planck Institute for Solid State Research in Stuttgart, Germany (1992-1993). There he worked on the ultrafast dynamics of light emission from semiconductor devices. His work on exciton radiative lifetimes in low-dimensional semiconductor structures helped establish the exciton-polariton picture as the accepted framework for understanding these effects. This work was cited on his Presidential Early Career Award for Scientists and Engineers which he subsequently received in 1997. In 1993, he took the position of Center Fellow at the Center for Ultrafast Optical Science at the University of Michigan, where he continued work on ultrafast dynamics. In 1995, he was appointed assistant professor of physics at Washington State University. Presently, he is an associate professor with the School of Electrical and Computer Engineering at the Georgia Institute of Technology, where his group works on theoretical and modeling issues ranging from the fundamental electronic and optical properties of novel semiconductor structures and materials to device applications in nonlinear and ultrafast optics and in terahertz technology. Citrin is presently serving as an Associate Editor of the IEEE Journal of Quantum Electronics.
