Abstract

Crystal defects in solid-state spintronic materials play a crucial role in altering the optical properties of their hosts, enabling widespread applications in the field of quantum information processing. While the majority of the leading platforms are inorganic, they come with limitations such as the challenging material preparations and insufficient amount of active spins. Here, pentacene-doped p-terphenyl (Pc:Ptp), an organic spintronic material with easy preparations and tailorable functionalities normally used for microwave quantum electronics, is demonstrated for the first time its ability of self-cavity laser emission at room temperature. The laser emission is characterized by strong polarization and anisotropy, attributed to the unique packing of the doped molecules (i.e., active spins) within the crystal. The optical coherence is found to be a figure of merit to distinguish the processes of the amplified spontaneous emission (ASE) and lasing in Pc:Ptp. This work highlights the potential of Pc:Ptp as a compact and efficient platform for light-matter interactions, offering significant promise for enhancing the performance of solid-state quantum devices based on the organic spintronic material.
