英文摘要	An optical communication signal source package and assembly for coupling optical signals to the end of an optical fiber (22) includes first and second semiconductor laser diodes (28, 30) capable of being operated in a redundant fashion for increased reliability or to provide wavelength division multiplexing for increases in bandwidth and information carrying capability. The laser duides are supported with their mounting flanges (38, 40) in a common plane and are oriented to provide beams (28A, 30A) of polarized light having perpendicular E-field vectors. A connector (32) carried by the support (26) positions the optical fiber at the target area where an optics system focuses the light beams. An optical coupling device such as a polarizing beam splitter (46) or a holographic beam separator is responsive to the orthogonal light beams to direct both light beams toward the optical fiber with minimum decrease in amplitude. The package includes no moving parts or highly frequency selective components. The package is employed in a compact communication signal coupling assembly permitting short electrical lead lengths and high circuit density.
