Active noise suppressor for multichannel optical systems

A multichannel optical system comprising:

• means for providing a plurality of optical paths;
• means for providing a beam of electromagnetic radiation;
• said beam of electromagnetic radiation being directed through a preselected one of said optical paths and having substantially all of said electromagnetic radiation being output therefrom, with the other said optical paths having substantially lesser amounts of said electromagnetic radiation being output therefrom;
• means for suppressing a signal, optically aligned with said plurality of optical paths, permitting said beam of electromagnetic radiation output from said preselected optical path to pass therethrough and preventing said substantially lesser amounts of electromagnetic radiation from passing therethrough;
• and
• said signal suppressing means comprising a plurality of vertical cavity semiconductor signal suppressor elements.
