Abstract
- We derive equations that quantify silicon Mach-Zehnder Interferometer (MZI) modulator impact upon optical link budget for NRZ transmissions based solely upon modulator extinction ratio (ER), the efficiency-loss figure of merit (FOM), and peak-to-peak drive voltage (Vpp). Our modulator link penalty equations transform the modulator efficiency-loss FOM from a simple device quality metric into a means of predicting how design and technology choices impact system margin. Our results indicate that, with a 17.8 V-cm FOM and 1 Vpp drive, designing an MZI to have an ER anywhere within the large range from 3.5-10 dB leads to nearly constant link margins, identical to within 0.5 dB.<br />Comment: 4 pages, 3 figures, 1 table
