Abstract
Over the past decade, spontaneously emerging patterns in the density of polaritons in semiconductor microcavities were found to be a promising candidate for all-optical switching. But recent approaches were mostly restricted to scalar fields, did not benefit from the polariton’s unique spin-dependent properties, and utilized switching based on hexagon far-field patterns with 60◦ beam switching (i.e. in the far field the beam propagation direction is switched by 60◦). Since hexagon far-field patterns are challenging, we present here an approach for a linearly polarized spinor field that allows for a transistor-like (e.g., crucial for cascadability) orthogonal beam switching, i.e. in the far field the beam is switched by 90◦. We show that switching specifications such as amplification and speed can be adjusted using only optical means.
