Description
We present the realization of a new type of laser diode based on surface-confined Tamm plasmon modes, offering an innovative approach for the design of optoelectronic sources that combine high optical performance with technological flexibility. Tamm plasmon modes are electromagnetic modes localized at the interface between a distributed Bragg reflector (DBR) and a metallic layer [1], merging key features of optical cavity modes and surface plasmons. In this approach, optical confinement is achieved through the lateral structuring of the metallic layer [2], which enables both efficient mode confinement and the realization of complex laser source geometries [3]. Importantly, the Tamm laser mode can be engineered and shaped without modifying the underlying DBR, providing additional freedom in device design and fabrication.
