Pin Diode Characteristics Experiment
OBJECTIVES
- To study the response of PIN diode, in the following conditions:
- Photocurrent (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 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 as photo diodes in PIN photodiode configuration and are very important in optical fiber communication.

Single Slit Experiment
OBJECTIVES
- To find the wavelength of a given laser using the slit of known width.
- To find the slit width knowing the wavelength of light used.
- Proving the concept of the Heisenberg uncertainty principle.
PRINCIPLE
Diffraction is a phenomenon of bending of waves when it encounters obstacles or narrow opening. A basic setup to observe diffraction consists of a laser, a slit, screen placed at a distance. The wavefronts are partially obstructed by the slit. The intensity distribution of the diffraction pattern consists of a series of light and dark fringes with the intensity distribution symmetric along the central axis. The primary peak is called the central maxima. The corresponding peaks are called secondary, and tertiary maxima. This is studied using the single-slit experiment.

Size of Particle Experiment
OBJECTIVES
- To measure the width/thickness of the given samples by analyzing the diffraction pattern.
PRINCIPLE
The characteristics of light such as interference and diffraction can be understood when light is studied as a wave phenomenon. Interaction of waves with matter results in either transmission, reflection, absorption, or diffraction of the wave. When the size of the matter is comparable to the wavelength of the wave that it interacts with, a phenomenon called diffraction occurs. Diffraction of light due to particles is a function of the size of the particle and the wavelength of the light incident. It is possible to measure the size of a particle by studying the diffraction patterns created by it.SOP1-C -

Energy Band Gap Experiment
OBJECTIVES
- To find the energy band gaps for different semiconductor diodes and LEDs
PRINCIPLE
At an absolute zero-degree temperature, semiconductors are pure insulators. As the temperature is increased thermal energy creates vibrations in the crystal lattice and a few electrons, which acquire sufficient vibrational energy break their covalent bond, become free, and move to the conduction band. The energy required to rapture the covalent bond is designated as energy gap EG and termed as energy gap or band gap energy.

Interferometer Experiment
Objectives
- To produce and observe the interference pattern.
- To measure the wavelength of laser source using the interferometer.
Principle
Phenomena of interference can be explained by the principle of superposition. Consider two E.M waves simultaneously propagating through the same region of space. The resultant electric field at any point in that region of space is the vector sum of the electric field of each wave. Depending on the strength of the resulting electric field at a point in space where the two waves superpose, we observe dark and bright regions in the interference pattern.
Key Features
- Easy to Setup – The apparatus is built on a sturdy and portable platform. The legs are height adjustable to aid leveling of the platform & precise optical alignment of the laser beam. All this reduces the time taken for setup and aids the ease of measurements.
- High quality beam splitter and reflective mirrors – The setup comes with 40 x 40 x 40mm beam splitter cube and 40 x 40mm (98% highly reflective) mirrors for clear fringe pattern.
- 1 micron step movement – The complex double lever mechanism enables a least count of 1 micron in movement of the fixed mirror. Measurement error is less than 5% in wavelength measurement.
