Abstract
One of the main hurdles of photonics is storing temporarily information directly from an optical stream. An ideal platform is that of VCSELs that, when externally driven by a coherent laser field and operated below threshold, can support stable localized light structures [1]. We demonstrate the switching on of an 11 µm (Full-Width-at-Half-Maximum, FWHM) localized optical structure inside a broad area (200 µm-diameter) VCSEL cavity through an electro-activated funnel waveguide structure in KLTN [2]. We are also able to show that the localized structure can be turned off by tuning the phase of the writing beam and then is bistable on a homogeneous background [3].
