Some refractive index variation is introduced into lateral structure of laser.

Question

Quizplus · Accepted Answer

Introducing refractive index variation into the lateral structure of a laser is a common method to confine the light in a specific region, enhancing the laser's efficiency and beam quality. This technique is used in various types of lasers, such as semiconductor lasers, to create a waveguide structure that guides the light along the laser cavity.
