Abstract
An apparatus includes a curved multimode polymer waveguide having at least one inflection point and a doped region being doped with an amplifying dopant. An optical pump source or electrical pump source is configured to excite the doped region and amplify the optical signal transmitting along the curved multimode polymer waveguide.
Claims20
An apparatus comprising:
- a curved multimode polymer waveguide having at least two inflection points and a doped region being doped with an amplifying dopant;
- and
- a pump source configured to excite the doped region.
A system comprising:
- a multimode polymer waveguide having a curved mode stripping path and a doped region being doped with an amplifying dopant, the curved mode stripping path removes one or more higher order optical modes, the multimode polymer waveguide defining a parabolic spiral or a Fermat's spiral that includes the curved mode stripping path;
- and
- an optical or electrical pump source configured to excite the doped region and amplify an optical signal transmitting through the multimode polymer waveguide.
An apparatus comprising:
- a curved multimode polymer waveguide having at least one inflection point and a doped region being doped with an amplifying dopant;
- a pump source configured to excite the doped region;
- and
- a crosstalk suppression element adjacent to the at least one inflection point.
