Design a circuit using TSAL6100 Infrared emmitter LED. The circuit will have a switch (i.e. a button), which controls the radiant power of the LED such that: the radiant power will be 2mW when the switch is on, and the radiant power will be 20mW when the switch is off. Use only a single DC power supply.

4 (a) “There are three types of optical fibers available for optic communication”. What are these three types and describe each. You may use diagrams to help you with your answers.  (b) Pin diodes and Avalanche photodiodes (APD) are detectors which are used to convert the transmitted light back into an electrical signal I. Describe the operating principles of a PIN diode and an Avalanche photodiode II. The quantum efficiency of APD is 80% for the detection of radiation at a wavelength of 0.9 μm. When the incident optical power is 0.5 μW, the output current from the device (after avalanche gain) is 11 μA. Determine the multiplication factor of the photodiode under these conditions. (c) A silica optical fibre with a core diameter large enough to be considered by ray theory analysis has a core refractive index of 1.480 and a cladding refractive index of 1.44. Determine: I. The critical angle at the core–cladding interface II. The acceptance angle in air for the fibre.
