Abstract
The invention is an optical switching device having a switching element which, in one aspect is a solid switching body to reduce beam spread, in a second aspect is trapezoidal in cross-section so that the optical channels selectively connected by the switching body are conveniently located on one side of the device, and in a third aspect is a retroreflective switching element that eliminates the need to achieve and maintain precise angular alignment between the switching body and the optical axes of the optical channels connected by the switching device.
