Question

1. The Diode emits Laser when it is -
A. Reverse Bias
B.Forward Bias
C.Homo-Junction
D. Heterojunction​

Answer 1

Explanation:

Laser diodes can directly convert electrical energy into light. Driven by voltage, the doped p-n-transition allows for recombination of an electron with a hole. Due to the drop of the electron from a higher energy level to a lower one, radiation, in the form of an emitted photon is generated.
