| Abstract: |
A novel technique for achieving SSB-SC is proposed for achieving high dynamic range in analog applications. The technique employs an intracavity modulator together with an intracavity filter that blocks the modulation sidebands from being re-circulated. Spurious-free dynamic ranges (SFDR) exceeding 120 dB/Hz2/3 is achieved using this novel technique. Development of a prototype photonics circuit with 20 GHz bandwidth and instantaneous bandwidth greater than 1 GHz will be demonstrated. |
| Benefits: |
Complex RF systems on naval aircraft will benefit greatly from the development of 20 GHz analog RF links with a dynamic range of 120 dB/Hz2/3. These specifications are well beyond any product commercially available today. IPITEK does not currently manufacture laser transmitters above the 1-2 GHz range used presently in the CATV and telecom industry. Successful completion of Phase I and Phase II will allow IPITEK to enter the broader "microwave over fiber" marketplace. |
