Boston AppliedTechnologies Incorporated (BATi) was formed in 2002 by the key managementand technical team formerly with Corning Applied Technologies (CAT), asubsidiary of Corning Incorporated. The mission of BATI is to developand manufacture novel materials-based devices for emerging photonic/electronicmarkets.
BATi's basictechnology (Materials Development Group) includes the state-of-the-artOptoCeramic® materials in bulk and thin-film forms, both forsolid-state light controlling devices. BATi's Photonics Group combinesits expertise in optics, fiber-optics, and packaging to produce low costand high performance photonic products for applications ranging from fiberoptic communications to optical sensors and instrumentation. BTAi's technologyis protected by more than 30 US and international patents and patent disclosures.

● Light Intensity Management Devices

Forlight intensity management, Boston Applied Technologies provides a completesolution through its EclipseTM line. The Eclipse™ Variable OpticalAttenuator (VOA) offers optical power control solutions for both single-wavelength,such as in pre-emphasis, and multi-wavelength, such as in EDFA, applications.The VOA is well received in the marketplace because of its high reliability(passed full Telcordia qualification) and high performance (the fastestVOA). No failure has been reported since the VOA first reached in themarket in 1999.

● Light Polarization Management Devices

BATi (and CAT) was one of the first companies thatintroduced polarization-controlling devices to the marketplace with nomoving parts. OptoCeramicTM technology enables high speed (200ns), solid-state light polarization management in a compact package. ThePolarization Controller/Polarization Transformer (PC/PT) converts anyinput state of polarization (SoP) to any output SoP by sending electronicsignals to each independent retardation plates. The Dynamic PolarizationRotator (DPR) rotates the light beam while preserves its polarizationproperty. The Polarization maintaining tap monitor (PM-tap) gives 3% to5% tap output of P- or S-polarization component through an integratedphotodetector. BATi's polarization sensor provides the fastest SoP detectionand enables high performance polarimeters.

● Wavelength Profiling Devices

The VariableGain Tilting Filter (VGTF) provides Wavelength Division Multiplexing (WDM)gain equalization and tilting for optical amplifiers with either a tiltedor a parabolic profile. The Dynamic Gain Flattening Filter (DGFF), basedon a harmonic filter design, dynamically smoothes out any non-linearityin optical amplifier gain curves and allows power equalization for DWDMsystems at a lower resolution, while the Dynamic Spectrum Equalizer (DSE)adjusts each wavelength channel individually and gives the highest resolutionin power equalization.

● Optical Switch

Boston AppliedTechnologies, Inc. (BATi) is a leadingmanufacturer of ultra-fast optical devices. Based on the revolutionaryelectro-optic material-OptoCeramicTM, BATi has developed avariety of nano-second, low loss light intensity, polarization and spectrummanagement devices. The Nanona™ switch is the new addition to BATi'sEclipse™, Acrobat™ and Equinox™ product portfolio.

BATi's Nanona™ ultra-fast and low loss optical switch redirects theoptical signal from one channel to another one at the speed faster than 50ns. The Nanona™ switch is a solid-state switch operatingin free-space architecture. It has lower optical insertion loss less 1dB, much faster speed and more reliable switching compared to competing opticalswitching technologies. The switches provide solutions to managing fiberoptic connections, monitoring optical performance and sharing vital resourcesfor a wide variety of applications in telecommunication networks, defense/government,medical /bio-technology and instrumentation industries.
