MEMS Tap/VOA Hybrid
DiCon's MEMS Tap/VOA Hybrid is based on a micro-electro-
mechanical system (MEMS) chip integrated with a thin film filter.
The thin film tap filter couples a portion of the input signal to an
output tap fiber while transmitting the rest of the input signal
onto a movable MEMS mirror. The MEMS mirror position
depends on the applied voltage, thereby adjusting the power level
coupled into the attenuator (VOA) output fiber.

Applications
MEMS Tap/VOA Hybrids are used in telecom modules which require
power level control and power monitoring. Examples of such modules
are VOA-MUX/DMUXes, OADMs with integrated power equalization,
Dynamic Band Equalizers, Dynamic Channel Equalizers and Fiber
Amplifiers.
