Abstract
An optical system includes a waveguide having a guiding core formed from erbium-doped yttrium aluminum garnet and a plurality of first cladding layers, wherein at least two of the first cladding layers are disposed adjacent opposite sides of the guiding core and a pump source for generating an electromagnetic radiation having a wavelength in the range of 900 to 1000 nanometers, wherein the pump source directs the electromagnetic radiation into at least the guiding core to pump the guiding core into an upper state.
