Evaluation and Characterization of Electro-Optic Components
Abstract
Mach-Zehnder modulators and optical switches are essential components in photonics links. This report provides an understanding of how external variables such as optical power, RF power, wavelength, and temperature independently affect the performance of these devices. For applications involving wide-temperature fluctuations, EO Space modulator AX-OK1-20-PFU-SFU-S will provide superior performance. However, for multiple wavelength applications, this advantage is mitigated by a quadrature bias drift of 0.35 volts per 10 nm. While modulator AZ-1x2-OK1-12-PFU-PFU functions independent of wavelength, the adverse temperature dependence is severe. In comparing the SW-1x2-SO-PFU-PFU and SW-1x2-P1-SFU-SFU optical switches, the pm-fiber switch provided an additional 10 dB of cross-talk suppression. Furthermore, the pm-fiber switch has a smaller differential switching voltage required to optimize the power back and forth between output channels.
