Abstract
An optical amplifier is provided from a body 21, at least part 25 of which is doped with a rare earth such as erbium. At least one waveguide 47 extends through the doped part of the body. Pump light 51 is input on a side face 35 of the body and is distributed in the body over the length of the waveguide 47. A reflective coating 57 may be provided away from the pump light input, including on the opposite face 37 to the pump light input, to multiply reflect pump light within the body 21 to distribute the pump light within the body. The body may be in the form of a slab.
