Application: Optical attenuator (Patent ID: US20230408882A1)
The patent filed by Telefonaktiebolaget LM Ericsson describes optical attenuators for telecommunications networks that utilize electrochromic devices to reflect or refract input optical signals with adjustable levels of optical attenuation. These optical attenuators can be controlled using a voltage controller, which can apply a voltage to the electrochromic device to adjust the optical attenuation levels.
Additionally, the optical attenuators may include features such as a photovoltaic cell to generate electrical power from the input optical signal, a buffer battery to store this generated power, and a photodiode sensor to monitor the output optical signal. The voltage applied to the electrochromic device can be determined based on the power generated by the photovoltaic cell or the monitoring results of the photodiode sensor. The patent also specifies that the electrochromic device can provide a resting optical attenuation level if no voltage is applied for a certain period, with the optical attenuation level range being between approximately 10% and 90%.
