Data sheet terra-Q 100GHz filters Features terra-Q 100 * Variable or fixed angle of incidence The Bookham Technology terra-Q narrowband filter product line is based on thin-film interference technology. These filters are produced with Bookham Technology's proprietary Advanced Energetic Deposition (AED) III technology. * C or L-band center wavelengths * Standard or Wide-Top passbands * Large adjacent channel isolation * Deep reflection isolation terra-Q 100 filters Bookham Technology offers a range of filtering solutions for 100GHz channel spacing. One grouping of specifications is intended for mux/demux applications where transmission and reflection loss are key parameters. Higher performance versions are available for optical add and drop multiplexing where deeper reflection notches are required in order to reduce coherent cross-talk. Wide-Top Versions In many applications, it is desirable to have an increased width pass band. This provides several application benefits: * Better cascadability of filters. * Lower Chromatic Dispersion near the filter's center wavelength * Additional passband width to accommodate high modulation bandwidth sources or chirped lasers. Variable or Fixed Angle of Incidence The lowest cost solution uses a variable angle of incidence package and a wider center wavelength tolerance. Fixed angle of incidence solutions are available with customer specified center wavelength tolerance. www.bookham.com Thinking optical solutions terra-Q 100 transmission and reflection terra-Q 100 Wide-Top T and R Preliminary Specifications* Parameter Symbol Unit Variable Variable Fixed High Perform Wide- AOI#1 AOI#2 AOI Variable AOI Top Transmision Parameters Center Wavelength at 0 angle of incidence (AOI) c nm 1460-1640 1460-1640 1460-1640 1460-1640 1460-1640 c Tolerance nm c 0.1 c 0.175 c 0.05 c 0.175 c 0.175 PBT nm c 0.15 c 0.21 c 0.15 c 0.20 c 0.21 -0.5dB Bandwidth BW0.5 nm >0.40 >0.42 >0.40 >0.40 >0.56 Maximum Loss over PBT ILmax dB <0.70 <0.70 <0.70 <0.70 <0.70 Loss Variation over PBT ILvar dB <0.30 <0.35 <0.30 <0.35 <0.30 Adjacent Channel Region AC nm c 0.60 c 0.57 c 0.60 c 0.59 c 0.54 Adjacent Chan.
