High Performance Enhanced Filters for the Optical Market (.doc)

From Thin Film Technology Corporation
 

 
Many new enabling optical modulation techniques rely on critical electrical filtering at both the front and back end of the electro-optical system. At the front end there are many emerging modulation techniques being developed. Optical Duo-binary systems with conventional electric components (NRZ Driver) require a low drive voltage modulator and an electrical filter exhibiting good return loss and group delay performance. At the back end there is an issue of tuning the receiver sensitivity to optimize for the spectral content of the data. These objectives have been achieved with "Enhanced Passive Bessel" filters.
