MEMS Tunable Filter
Description
Optoplex’s MEMS Tunable Optical Filter is based on a patented micro-optic design with MEMS tuning technology. It is an integrated module consisting of a MEMS chip, micro-optics and control electronics and interface. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tunable optical filter directs a selected channel to the Output-Port (OUT). Wavelength (frequency) tuning is achieved by changing driving voltage applied to the MEMS chip, via the control electronics and the built-in firmware.
The MEMS tunable filter offers high optical filtering performance: low insertion loss and high isolation. Moreover, the MEMS tunable filter provides high-speed tuning that is highly demanded in many applications. The standard optical tunable filter product family includes 30- and 60-GHz typical 3dB bandwidth.
Optoplex’s MEMS tunable filter is ideal for applications from wavelength locking, optical channel monitoring and optical add/drop in optical communications; optical filtering and wavelength management in fiber sensing and spectroscopic instrumentation.
