"spatial control of room-temperature, high-speed, all-optical polariton condensates... without relying on excitation profiles of polaritons, introducing additional copolymer layer (remaining nonresonant) within weakly coupled cavity... partially saturating optical absorption using 2-color beam excitation enabled ultrafast modulation of effective refractive index simultaneously with formation of polariton condensate dissipation... control over spatial profile, density, and energy... lateral design photonic chip"
