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 …

If laser light is fed through an interferometer, as sketched in Fig. 8.1, the power transmission from the input to the output depends on the actual optical frequency v. If a laser exhibits …
