Voltage-Controlled Optical Filters
The Lumentum VCF series is a voltage-controlled tunable band pass filters that can be used for amplified spontaneous emission (ASE) suppression of optical signals and for single-channel demultiplexing from a multichannel dense wavelength division multiplexing (DWDM) optical signal stream. The VCF can also be used in flexible and dynamic wavelength optical add/drop applications. The VCF uses hermetic sealing for increased resistance to environmental extremes. The VCF series offers excellent optical performance in either C or L band.
The center wavelength selection is precisely tuned using a stepper motor driven by an external integrated circuit controller. The driver moves the filter up and down in uniform steps in the center wavelength, to provide high resolution. The VCF is compact in size and can easily be mounted on a printed circuit board (PCB).
The transmission spectrum of the VCF is optimized for low insertion loss, high rejection, and low chromatic dispersion.
