Comparison Between Photodetector and Photodiode
Photodetector | Photodiode |
---|---|
Photodetector is a device which sense light radiation. | Photodiode is a photodetector but it also detects the light intensity. |
It is used to detect light radiations. | It is light sensitive diode made of semiconductor. |
It does not have amplifier to detect the light. | Photodiodes have amplifiers connected in them for the detection of light having low level of intensity. |
It is made of compound semiconductor having 0.73eV band gap. | It is made of p-type. n-type, or p-n type of semiconductor junctions. Sometimes, It also have intrinsic junction. |
Its response time is slow. | Its response time is fast. |
Photodetector
A photo is nothing but light. A detector is nothing but a device that detects something. Therefore, we can directly conclude that a photodetector can be defined as a device that is used to detect light radiations by absorption. In this Article, We will be going through Photodetector, We will start our Article with What is Photodetector?, Then we will go through its brief Working, then we will go through its properties and go through all the types, At last, we will conclude our Article with Advantages, Disadvantages and Some FAQs.
