Webster, M and Sargent, LJ and Dowd, P and Heard, PJ and White, IH and Penty, RV and Tan, MRT and Cunningham, DG (1998) Mode-controlled vertical cavity surface emitting lasers for bandwidth enhancement of multimode fibre links. Conference on Lasers and Electro-Optics Europe - Technical Digest. 33-.Full text not available from this repository.
A GaAs Vertical Cavity Surface Emitting Laser (VCSEL) that generates controlled modes offset from the center is described. The device is modulated with a 27-1 pseudo-random bit sequence and its output is transmitted along a 1 km length of multimode fiber (MMF). Open eyes are obtained for data rates as high as 1.4Gb/s. The transmission bandwidth increases by a factor of 4 over over-filled launch (OFL). This enhancement is stable against environment influences on the fiber.
