在“虚”光激发过程中由外部电路引起的光子能量耗散

Photon-energy dissipation caused by an external electric circuit in "virtual" photo-excitation processes

Akira Shimizu, Masamichi Yamanishi

摘要:

我们考虑在“虚激发”状态下由光脉冲产生电脉冲。电子系统,它是任何电光材料,包括由直流电场偏置的量子阱结构,被假定为耦合到外部电路。结果表明,除了通常的自相位调制外,光子频率还发生了额外的红移,而光子数是守恒的。在外部电路中消耗的焦耳能量仅由额外的红移提供。

英文摘要:

We consider generation of an electrical pulse by an optical pulse in the ``virtual excitation'' regime. The electronic system, which is any electro-optic material including a quantum well structure biased by a dc electric field, is assumed to be coupled to an external circuit. It is found that the photon frequency is subject to an extra red shift in addition to the usual self-phase modulation, whereas the photon number is conserved. The Joule energy consumed in the external circuit is supplied only from the extra red shift.
