In recent years there have been a significant number of demonstrations of small metallic and plasmonic lasers. The vast majority of these demonstrations have been for optically pumped devices. Electrically pumped devices are advantageous for applications and could demonstrate concepts not amenable for optical pumping. However, there have been relatively few demonstrations of electrically pumped small metal cavity lasers. This lack of results is due to the following reasons: There are limited types of electrically pumped gain medium available. There is a significantly greater level of complexity required in the fabrication of electrically pumped devices. Finally, the required components for electrical pumping restrict cavity design options and furthermore make it intrinsically more difficult to achieve lasing. This review looks at the motivation for electrically pumped nanolasers, the key issues that need addressing for them to be realized, the results that have been achieved so far including devices where lasing has not been achieved, and potential new directions that could be pursued.

“…Both optically [4] and electrically [5] pumped gain media can be used for the active control of SPPs, whereas the latter is especially promising for highdensity optoelectronic integration. In an active SPP device with electrically-pumped multiple quantum wells (MQWs) as the gain medium, the interface-bounded SPP mode requires MQWs in the modal field vicinity so as to maximize the modal gain [6]. Thus, the undoped separate confinement heterostructure (SCH) layer serving for carrier confinement has to be kept thin [7].…”

The influence of Au/Ni-based contact formed on a lightly-doped (7.3×10 , Zn-doped) InGaAsP layer for electrical compensation of surface plasmon polariton (SPP) propagation under various rapid thermal annealing (RTA) conditions has been studied. The active control of SPP propagation is realized by electrically pumping the InGaAsP multiple quantum wells (MQWs) beneath the metal planar waveguide. The metal planar film acts as the electric contact layer and SPP waveguide, simultaneously. The RTA process can lower the metal-semiconductor electric contact resistance. Nevertheless, it inevitably increases the contact interface morphological roughness, which is detrimental to SPP propagation. Based on this dilemma, in this work we focus on studying the influence of RTA conditions on electrical control of SPPs. The experimental results indicate that there is obvious degradation of electrical pumping compensation for SPP propagation loss in the devices annealed at 400 o C compared to those with no annealing treatment. With increasing annealing duration time, more significant degradation of the active performance is observed even under sufficient current injection. When the annealing temperature is set at 400 o C and the duration time approaches 60s, the SPP propagation is nearly no longer supported as the waveguide surface morphology is severely changed. It seems that eutectic mixture stemming from the RTA process significantly increases the metal film roughness and interferes with the SPP signal propagation.

“…For example, on the semi-infinite metal surface, SPP mode cannot exist within the frequency range of [ 1 , 7 ], where ω p is the plasma frequency of metal, ω ∞ is the background permittivity of metal, and ε 1 is the permittivity of semi-infinite dielectric upon the metal. Dielectrics with large permittivity ε 1 , such as Si or GaAs which are well used in some functional SPP devices [ 8 , 9 ], would lead to the decrease of ε sp and the cutoff of SPP mode. In some cases, even though SPP mode is not cutoff, the surrounding with large permittivity would result in extremely large propagation loss at certain optical frequency range.…”

Extending the Frequency Range of Surface Plasmon Polariton Mode with Meta-Material

et al. 2016

The frequency range that surface plasmon polariton (SPP) mode exists is mainly limited by the metal material. With high permittivity dielectrics above metal surface, the SPP mode at high frequency has extremely large loss or can be cutoff, which limits the potential applications of SPP in the field of optical interconnection, active SPP devices and so on. To extend the frequency range of SPP mode, the surface mode guided by metal/dielectric multilayers meta-material has been studied based on the theory of electromagnetic field. It is demonstrated that surface mode not only could be supported by the meta-material but also extends the frequency to where conventional metal SPP cannot exist. Meanwhile, the characteristics of this surface mode, such as dispersion relation, frequency range, propagation loss and skin depth in meta-material and dielectrics, are also studied. It is indicated that, by varying the structure parameters, the meta-material guided SPP mode presents its advantages and flexibility over traditional metal one.
