Hakiolu, T.2016-02-082016-02-0820090953-8984http://hdl.handle.net/11693/22779Based on Khodas et al (2004 Phys. Rev. Lett. 92 086602), we propose a device acting like a controllable prism for an incident spin. The device is a large quantum well where Rashba and Dresselhaus spin-orbit interactions are present and controlled by the plunger gate potential, the electric field and the barrier height. A totally destructive interference can be manipulated externally between the Rashba and Dresselhaus couplings. The spin-dependent transmission/reflection amplitudes are calculated as the control parameters are changed. The device operates as a spin prism/converter/filter in different regimes and may stimulate research in promising directions in spintronics in analogy with linear optics. © 2009 IOP Publishing Ltd.EnglishBarrier heightsControl parametersDestructive interferencesLinear opticsPlunger gatesQuantum wellsSpin-orbit interactionsSpintronicsControl system analysisElectric fieldsPrismsSpin dynamicsArticle10.1088/0953-8984/21/2/0260161361-648X
