For the first
time, polarization-preserving, high-speed attenuation is available in
a compact package. Boston Applied Technologies' EclipseTM series
of Polarization Maintaining Variable Optical Attenuator (PM-VOA) maintains
constant polarization output regardless of wavelength and level of attenuation.
Based on the revolutionary OptoCeramicTM electro-optic technology,
the PM-VOA achieves very high-speed performance (typical transition time
of less than 30 microseconds) in a compact solid state device. For added
convenience, the PM-VOA includes an integral tap/output monitor and a
photodetector. This eliminates the need for an external polarization-maintaining
coupler and photodetector, substantially reducing cost and space requirements.
