Why do MEMS optical switches require pre-bias voltage
RF MEMS components are biased electrostatically using a bipolar NRZ drive voltage, as shown in Fig. 2, in order to avoid dielectric charging and to increase the lifetime of the device. Electrostatically actuated RF MEMS components offer low insertion loss and high isolation, linearity, power handling and Q factor, do not consume power, but require a high control voltage and hermetic single-chip packaging (thin film capping, LCP or LTCC packaging) or wafer-level packaging (anodic. Optical switches are components in a fiber-optic communi-cations network that direct light beams from one optical fiber to another. Throughout this paper, the term “optical switch” shall refer only to switches that manipulate light beams directly. However, both of them have shown promises in. egarded as infinite for today's applications. O-E-O switches first convert the input optical signal to an elec ronic. These types of MEMS switches utilize electrostatic actuation to change the signal path and generally require two independent voltages to switch between the two ports. 4V and provides an extinction ratio above 15dB within a 34 nm bandwidth in the C-band.
