Convertibility Potential for a Condensate Bound with Thermalized Light

Nature Photonics 11, 9 | Published: September 1, 2017 | doi: 10.1038/nphoton.2017.139

Quantum vapor within a lattice potential is becoming a powerful platform for simulating solid physical phenomena, such as Mott insulator transitions. Unlike with low-temperature atoms, photon-based platforms such as photonic crystals, bound waveguides, lasers, etc. have many things that do not function in heat balance states. There are demonstrations of polariton lattice experiments and photon condensates as advancements towards photonic simulators with solid equilibrium effects. Here, we demonstrate a method of forming light convertibility micropotential using thermooptical imprinting on a pigmented polymer solution in a high-finesse microresonator. We investigated the idiosyncrasies of a single-potential well and a double-potential well, and observed a change in structure of sufficient quality in a Bose-Einstein condensate with light thermalization. Since the resultant light-light interaction was investigated, in addition to observing a tunnel junction between sites, it is a good candidate for directly populating an entangled photonic multibody state. Here, we demonstrated scalability, and thermooptic imprinting suggests ways to create new convertible microstructures in photonics.
