AgileWaveTM TUNABLE BANDPASS FILTER
Description
CiDRA has applied its innovative optical waveguide
technology to extend the application of Bragg grating
based filters to bring tunable functionality and wavelength
agility to the optical network.
Our AgileWaveTM tunable bandpass filter is a digitally
programmable, tunable grating module that can be
integrated with other optical components to enable optical
routing, conditioning and monitoring of DWDM channels.
Based on CiDRA’s proprietary optical waveguide technol-
ogy and Bragg grating packaging technology, the device is
accurately settable to any wavelength within its operating
range (C- or L-Band) with a simple digital command.
The key functional feature of the device is that tuning is
accomplished in an “optically open-loop” mode, with
exceptional precision and repeatability, without wavelength
referencing or spectrum analysis.
CiDRA’s proprietary waveguide platform technology
overcomes fiber attachment and reliability problems that
plague other tunable grating approaches, achieving
unprecedented stability, repeatability and reliability.
