Abstract
A directable laser transmission module incorporating a vertical cavity surface emitting laser (VCSEL) array ( ) and a refractive optical element (ROE) array ( ) is provided. Each VCSEL ( ) generates a laser beam ( ) having an axis ( ) substantially perpendicular to a substrate ( ). The ROE array ( ) is positioned proximate the VCSEL array ( ) substantially parallel to the substrate ( ) so that each laser beam ( ) is intersected by only one ROE ( ). Each of a plurality of communication signals is carried by at least one laser beam ( ). An laser beam ( ) carrying a one-beam signal is intersected, collimated, and directed by a single ROE ( ) to its predetermined reception location ( ). A plurality of laser beams ( ) carrying a single multiple-beam signal is intersected, collimated, and directed by multiple ROEs ( ) to a common predetermined reception location ( ).
