Basic Principles of Light Emission in Semiconductors, with monolithic (or hybrid) integration. Also, LED’s and laser diodes are widely used in fiber-optic applications, because they can be modulated at high frequencies and can be efficiently coupled to the micrometer-size wave-guiding core of the fiber.

Distributed Feedback Lasers,isrupted, which leads to difficulties in fabricating electrical connections and heat sinks. An alternative approach, which utilizes distributed feedback (DFB) from a Bragg-type diffraction grating, provides a number of advantages while still utilizing a planar surface geometry.
