WebBackground information on Extinction Ratio . Commonly called out in optical telecommunication standards, ER is a measure of modulation depth, and can be used for example as a figure of merit of an optical modulator. The most common definition is the ratio of power between the logic One and logic Zero. See Figure 1. portsmouth water leakbot
On-Chip High Extinction Ratio Single-Stage Mach-Zehnder
WebAbstract. The purpose of this application note is to define optical modulation amplitude (OMA) and how it relates to other parameters such as extinction ratio and average power. Further, this application note will clarify the trade-offs between specifying OMA versus extinction ratio and explore appropriate specification ranges for each.
