Angle-resonant stimulated polariton amplifier
We experimentally demonstrate resonant coupling between photons and excitons in microcavities which can efficiently generate enormous single-pass optical gains approaching 100. This new parametric phenomenon appears as a sharp angular resonance of the incoming pump beam, at which the moving excitonic polaritons undergo very large changes in momentum. Ultrafast stimulated scattering is clearly i...
متن کاملTerahertz Optoelectronics with Surface Plasmon Polariton Diode
The field of plasmonics has experience a renaissance in recent years by providing a large variety of new physical effects and applications. Surface plasmon polaritons, i.e. the collective electron oscillations at the interface of a metal/semiconductor and a dielectric, may bridge the gap between electronic and photonic devices, provided a fast switching mechanism is identified. Here, we demonst...
متن کاملScattering of terahertz radiation on a graphene-based nano-antenna
Scattering of the terahertz radiation on a graphene-based nano-antenna is considered. Different electromagnetic models of graphene are discussed and applied to calculate extinction, scattering and absorption cross sections of the nanoantenna. Scattering resonances in the terahertz band are identified as longitudinal Fabry-Perot resonances of surface plasmon polaritons supported by the graphene ...
متن کاملTunable surface-plasmon-polariton-like modes based on graphene metamaterials in terahertz region
Plasmonic response in graphene-based metamaterials show great potential for terahertz (THz) wave manipulation. In this work, we study the tunable surface-plasmon-polariton-like modes based on graphene complementary split ring resonators (CSRRs) in THz region. Our study suggests that these modes can be generated by graphene plasmonic metamaterials due to the diffraction coupling of surface plasm...
متن کاملContinuous wave observation of massive polariton redistribution by stimulated scattering in semiconductor microcavities
A massive redistribution of the polariton occupancy to two specific wave vectors, zero and approximately 3.9x10(4) cm(-1), is observed under conditions of continuous wave excitation of a semiconductor microcavity. The "condensation" of the polaritons to the two specific states arises from stimulated scattering at final state occupancies of order unity. The stimulation phenomena, arising due to ...
