  • Optical module has poor extinction ratio at high temperature

    Optical module has poor extinction ratio at high temperature

    The temperature-dependent variables in an optical module can cause large variations in the extinction ratio and average power, which can lead to poor module performance at elevated temperature. Use of the methods described here minimizes the variations of these parameters. One parameter, extinction ratio, is used to describe optimal biasing conditions and how efficiently available laser transmitter power is converted to. Among them, Optical Modulation Amplitude (OMA) is a central figure of merit for digital (on-off) modulation schemes. As design/test margins get tighter, the challenges of making accurate and repeatable extinction ratio measurements become more apparent.
