Abstract:

This article describes how the far-field radiation distribution and power varies with the geometrical parameters of immersion lenses made from silicon (n¯=3.4) and chalcogenide glass (n¯=2.4) mated with LEDs (λ=3.4µm) based on indium antimonide (n¯=3.5) and estimates the efficiency of using such devices in miniature optical systems.
