Advantages and disadvantages of avalanche photodiode

There are some important advantages of avalanche photodiode are given below,

• The main advantage of the avalanche photodiode is it has a greater level of sensitivity.

There are some important disadvantages of avalanche photodiode are given below,

• The avalanche photodiode has much higher operating voltage may be required.
• The output is non linear due to avalanche process.
• Avalanche photodiode produce much higher level of noise.
