  • Directable laser transmission module
    Patent number: 6412989
    Abstract: A directable laser transmission module incorporating a vertical cavity surface emitting laser (VCSEL) array (28) and a refractive optical element (ROE) array (36) is provided. Each VCSEL (30) generates a laser beam (32) having an axis (44) substantially perpendicular to a substrate (42). The ROE array (36) is positioned proximate the VCSEL array (28) substantially parallel to the substrate (42) so that each laser beam (32) is intersected by only one ROE (34). Each of a plurality of communication signals is carried by at least one laser beam (32). An laser beam (32) carrying a one-beam signal is intersected, collimated, and directed by a single ROE (34) to its predetermined reception location (24). A plurality of laser beams (32) carrying a single multiple-beam signal is intersected, collimated, and directed by multiple ROEs (34) to a common predetermined reception location (24).
