BATI

Acrobat^TM Light Polarization Management Devices
BATI (and CAT) was one of the first companies that introduced polarization-controlling devices to the marketplace with no moving parts. OptoCeramic^®technology enables high speed (200 ns), solid-state light polarization management in a compact package. The Polarization Controller/Polarization Transformer (PC/PT) converts any input state of polarization (SoP) to any output SoP by sending electronic signals to each independent retardation plates. The Dynamic Polarization Rotator (DPR) rotates the light beam while preserves its polarization property. The Polarization maintaining tap monitor (PM-tap) gives 3% to 5% tap output of P- or S-polarization component through an integrated photodetector. The Polarization Control Module (PCM) adds PM-tap, electronics, and control algorithm to a PC/PT to give a complete packaged system with fixed linear polarized light output. BATI‘s polarization sensor provides the fastest SoP detection and enables high performance polarimeters. Products in the Acrobat^TM family are:

Equinox^TM Wavelength Profiling Devices
The Variable Gain Tilting Filter (VGTF) provides Wavelength Division Multiplexing (WDM) gain equalization and tilting for optical amplifiers with either a tilted or a parabolic profile. The Dynamic Gain Flattening Filter (DGFF), based on a harmonic filter design, dynamically smoothes out any non-linearity in optical amplifier gain curves and allows power equalization for DWDM systems at a lower resolution, while the Dynamic Spectrum Equalizer (DSE) adjusts each wavelength channel individually and gives the highest resolution in power equalization.
