✦ Synopsis
The use of wavelength division multiplexing in free air applications requires the use of selective receivers for wavelengths beyond the absorption range of silicon, i.e. for wavelengths greater than 1100 nm. The detector materials and semiconductor ®lters used there are cost-intensive, therefore the area size of the receiver diode is a signi®cant factor from the economic point of view. The introduction of the diode eciency Z provides an evaluation criterion for determining a reasonable size of the sensitive area.
