Claim Text:
1. An apparatus comprising: a polymer waveguide having a doped region separating a first un-doped region and a second un-doped region, the doped region being doped with an amplifying dopant, the first un-doped region having a first height and a first width and a second un-doped region having a second height and a second width, the second width being less than the first width; and an optical pump source to pump the doped region and allow light to transmit from the first un-doped region to the second un-doped region when the optical pump illuminates the doped region and to not allow light to transmit from the first un-doped region to the second un-doped region when the optical pump does not illuminate the doped region.
