Abstract
Embodiments relate to optical switching devices. In embodiments, the optical switching devices are implemented in a silicon substrate and comprise an absorbent element selectively movable into and out of the evanescent field of a light beam which passes through a lamella. The absorbent element attenuates the evanescent part of the light beam such that the beam can be switched on and off by movement of the absorbent element.
