Abstract :
A new form of optical waveguide, the gain/loss waveguide (GLW), is proposed and demonstrated through numerical simulation. Both step- and photonic crystal gain/loss fibres with no variation in the real part of the refractive index are shown to be feasible. The implications in designing novel waveguides and devices are discussed.
