2005 International Topical Meeting on Microwave Photonics, 2005•ieeexplore.ieee.orgWe report achieving a record low noise figure for an amplifierless fiber-optic link—≤ 15 dB
over the frequency range 1.0–9.5 GHz—via a combination of a low-V π Mach-Zehnder
modulator with two antiphase outputs, a high-power laser, and a balanced photodetector
pair. We also present a complete model for this link that predicts its measured performance
to within 1 dB.
