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.

Abstract
An optical communication system using a relatively large-area vertical-cavity surface-emitting laser. The laser has an opening larger than about eight micrometers and is coupled to a multimode optical fiber. The laser is driven into multiple transverse mode operation, which includes multiple filamentation as well as operation in a single cavity.
