Telecommunication wavelength confined Tamm plasmon structures containing InAs/GaAs quantum dot emitters at room temperature

摘要： We experimentally demonstrate gold microdisc structures that produce con?ned Tamm plasmons (CTPs)— interface modes between a metal layer and a distributed Bragg re?ector— resonant around 1.3 μm. Quantum dots grown within the structures show an order of magnitude increase in the photoluminescence emitted at room temperature. Varying the disc diameter, we show spectral tuning of the resonance and measure the dispersion relation as evidence of mode con?nement. The simplicity of fabrication and tuneability of these structures make CTPs an ideal platform for making scalable telecom devices based on quantum dots.
