Abstract :
Antimony based materials have the advantage of having the capability of detecting the mid-infrared wavelength (2 to 5 mum) because of its interesting optoelectronic properties. In this paper we have theoretically studied the noise performance of an In0.10Ga0.90Sb avalanche photodiode to examine its suitability as a detector in optical receiver units. We show that at optimum gain such a device has a low value of excess noise factor and a moderate signal to noise ratio. For a digital system the device exhibits a very low value of bit error rate which makes it suitable for using as a photo-detector in mid-infrared region.
