Query: Polychromatic polariton laser selector switch   Integration of optical elements into scalable chips has been at the center of
a large effort in recent years. Concurrently, the separation between the
diverse functions, namely switches, detectors or emitters increases
significantly the final number of components on chip. Such technical
limitations may be overcome by introducing agile devices able, for example, to
simultaneously detect, process and emit a coherent signal. Such a pathway has
been explored with different approaches that bear advantages and drawbacks.
Polaritons have often been proposed as promising candidates for multifunctional
devices. Here we present an optical switch based on polariton lasing. An
incident monochromatic signal is channeled into several polariton laser beams
at different wavelengths by a novel relaxation mechanism which combines
bistability, phonon interactions, long polariton lifetime and bosonic
stimulation. We demonstrate spin logic operations conserving the original
polarization state that is fully imprinted onto the coherently emitted signals.
