Pin Diode Characteristics Experiment
KEY FEATURES
- Precise Optical Alignment: The optical alignment of the components is attained by optical bench, the setting up time is faster and experimentation is easy.
- Fine and Easy Light Intensity Adjustment: Light intensity adjustment is done via use of two polarizers. This helps in easier and fine light intensity adjustments.
- Simple and Easy Connections: The color-coded terminals on the various components aids in the ease of connections thus reducing the setup time.

Description
OBJECTIVES
- To study the response of PIN diode, in the following conditions:
- Photo current (Iph) vs Applied voltage at constant irradiance (Φ) under Reverse biased condition of the PIN diode.
- Current (I) vs Voltage (V) under forward bias condition of the PIN diode.
PRINCIPLE
The PN-Junction diodes, though are versatile, have a few limitations regarding the amount of current they could handle before breakdown and also have low switching frequency, low power handling capacity and low quantum efficiency. To overcome all these issues PIN diode was designed. PIN diodes are also extensively used a photo diode in PIN photo diode configuration and are very important in optical fiber communication.
