1. An optical communication network comprising:

  • a vertical-cavity, surface-emitting semiconductor laser structure having an aperture larger than eight micrometers through which an optical signal may be emitted;

    a power supply that provides a bias current to drive the laser into a multiple transverse mode of Operation in which the laser is responsive to a signal carrying data to provide an optical signal modulated with the data and to emit the optical signal through the aperture; and

    a multimode Optical medium optically coupled to the laser to carry the optical signal from the laser to a remotely-located receiver.
