Claims
- 1. A modulator comprising:
a plurality of branches; first and second RF electrodes; a first plurality of RF delay elements coupled to said first RF electrode and a second plurality of RF delay elements coupled to said second electrode; and, a plurality of electro-refractive resonant elements each being respectively coupled to a corresponding one of said RF delay elements and evanescently coupled to at least one of said branches.
- 2. The modulator of claim 1, wherein said modulator is an interferometer.
- 3. The modulator of claim 2, wherein said interferometer is a Mach Zehnder interferometer.
- 4. The modulator of claim 1, wherein electrical and optical signals propagating down said branches are substantially synchronized.
- 5. The modulator of claim 1, wherein said RF delay elements substantially synchronize electrical signals propagating through said device with optical signals propagating through said device.
- 6. The modulator of claim 1, wherein capacitive properties of each of said resonant elements is substantially negligible so as not to electrically load either of s RF inputs.
- 7. The modulator of claim 1, wherein each of said resonant elements comprises a ring resonator.
- 8. The modulator of claim 7, wherein each of said ring resonators is an elongated ring resonator.
- 9. The modulator of claim 1, wherein said modulator is an electro-refractive Mach-Zehnder device and each of said branches is an arm of said device.
- 10. The modulator of claim 1, wherein said RF electrodes are configured in a push-pull configuration.
