Abstract
An add-drop filter for transmitting at least one signal is provided. The add-drop filter includes at least two optical waveguides capable of carrying the at least one signal, and at least one active resonator coupled between the optical waveguides, wherein the at least one active resonator provides gain that counteracts losses for the at least one signal.
Claims20
An add-drop filter for transmitting at least one signal, the add-drop filter comprising:
- at least two optical waveguides capable of carrying the at least one signal;
- and
- at least one active resonator coupled between the optical waveguides, wherein the at least one active resonator provides gain that counteracts losses for the at least one signal.
An optical communication system comprising:
- an add-drop filter for transmitting at least one signal, the add-drop filter comprising:
- at least two optical waveguides capable of carrying the at least one signal;
- and
- at least one active resonator coupled between the optical waveguides, wherein the at least one active resonator provides gain that counteracts losses for the at least one signal;
- and
- a gain stimulation device coupled to the add-drop filter, the gain stimulation device configured to provide a gain stimulation signal that excites a gain medium of the at least one active resonator.
3 more elements
A method of transmitting at least one signal through an add-drop filter, the method comprising:
- directing the at least one signal into the add-drop filter, wherein the add-drop filter includes at least two optical waveguides, and at least one active resonator coupled between the optical waveguides;
- and
- providing, using the at least one active resonator, gain that counteracts losses for the at least one signal as the at least one signal is transmitted through the add-drop filter.
