  We propose a technique to control the beam direction of a dielectric optical
micro-prism structure by properly designing its geometry. We show that by
selectively choosing the slope of a high index micro prism, the direction of
the radiated beam from the tip can be controlled in the broadside direction of
the prism structure. We propose an easy fabrication method to integrate such
broadside beam routers on a Si platform. We also propose a demonstrate a
technique to build the beam router on an elastic PDMS platform which
demonstrates stress induced beam scanning in the broadside This specific
feature of beam direction control can find application in free space optical
interconnects, plasmonics, solar cells, detectors, optical sensing etc.
