“…According to such a mechanism, some depolarization methods have been investigated in the past. These methods involve the use of tensile-strained barriers, 17 tensile-strained quantum wells, 11,18 delta-strained auxiliary layers, 19,20 hybridstrain quantum wells, [21][22][23][24] and vertically-stacked quantum dots. [25][26][27] We notice that these previous approaches have a common point: that is, the whole active structure is some sort of combination of multiple quantum-confined layers that have different types of strain or a mixture of lattice-matched quantum-confined layers with tensile-strained layers to obtain both TE and TM optical signals.…”

“…However, in normal lattice matched MQW structures, the TE polarization field gain is higher than that of the TM's [16]. For high fidelity amplification of the hybrid plasmonic wave, it is necessary to adopt the strain MQW because of its equal gain about the TE and TM field [17].…”

We propose a hybrid gap plasmonic traveling wave amplifier (TWA) with electrically pumped multiple quantum wells (MQW). This TWA has deep sub-wavelength mode field scale and works at 1310 nm window. For the polarization-independent amplification we design the InGaAlAs tensile-strain MQW. Furthermore we analyze this plasmonic TWA’s optical, electrical and thermal characteristics by finite element method. First we get the suitable trade-off point between the affordable mode propagation loss and moderate mode field size by adjusting the gap width and height. Second we find that the narrower the MQW, the higher the MQW local gain. Third, our device has good thermal performance as the plasmonic wave power is less than 5 μw. Simulation results suggest that the independent polarization gain appears at 1317 nm wavelength. At this wavelength 3.60 cm −1 mode gain and 161 nm mode width are obtained as the 9.39 kA cm−2 injection current and 10 nm × 240 nm gap size.
