|
| The iVOATM product family provides a solid-state, single chip solution for variable optical attenuator (VOA) arrays. The integrated photonic chip is based on DuPont Photonics’ library of proven, Telcordia-qualified, optical building blocks and planar lightwave circuit (PLC) integration technology. The iVOATM is actuated with electrical power based on thermo-optics. The iVOATM family of VOA arrays provides a scalable solution for variable optical attenuation with low cost, high performance, small size, and low power dissipation. The family comprises of both “normally open” and “normally dark” VOA arrays. They allow for high accuracy attenuation in open loop operation, eliminating the need for dedicated optical power monitors. The iVOATM products are ideal for reconfigurable add drop multiplexer (ROADM), wavelength blocker, VMUX, and dynamic gain equalizer (DGE) applications. |
