Discovery Semiconductors Balanced Photodiodes with Integrated Optical Delay Line


Ewing, NJ - January 19, 2005Optical Delay Line Lab Buddy

Lab Buddy” is a small lightweight bench top O/E instrument which incorporates Discovery’s family of wide bandwidth photodiodes and receivers. Our newer Balanced Photodiode Lab Buddy model can now be ordered with an option of integrated variable optical delay line.

The reason for integrating optical delay line is to match precisely the path lengths of the two photodiodes in a balanced version. One meter of fiber length is approximately 5 nano-seconds of delay, so 1 millimeter of fiber length is approximately 5 pico-seconds of delay. This path length matching is critical for 40 Gb/s applications, where the bit period is 25 pico-seconds.
