  We experimentally demonstrate gold microdisc structures that produce confined
Tamm plasmons (CTPs), interface modes between a metal layer and a distributed
Bragg reflector, resonant around 1.3 {\mu}m. 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 confinement.
The simplicity of fabrication and tuneability of these structures make CTPs an
ideal platform for making scalable telecom devices based on quantum dots.
