Question:

A particular LED has a 4 ns injected carrier lifetime. When no modulation current is applied to the device, the optical output power is 0.25 mW for a specified dc bias. Assuming parasitic capacitances are negligible.

(i) Plot the optical output power when the LED is modulated at frequencies ranging from 20 MHz to 200 MHz.

(ii) What is the 3-dB optical bandwidth and 3-dB electrical bandwidth of the device.
