Abstract :
An 835 nm superluminescent diode with a spectral width of 8 nm is shown to reduce SNR fluctuations due to modal noise significantly in PFM optical video transmission. An SNR of 56 dB and DG/DP of 06%/0.3° are achieved over 5 km with a frequency deviation of only 400 kHz. The SNR fluctuation is less than 0.05 dB.
