Modified Optical Properties of Semiconductor Quantum Dots by Photonic Structures

Specially designed photonic structures, such as photonic crystals, can prevent light from propagating in certain directions with specified frequencies.Such photonic stsuctures exhibit many unique features that are highly desirable for the manufacture of photonic integrated circuits.There has been great interest in controlling light-emitters via photonic structures, which can partially suppress and redirect spontaneous emission.Encapsulating an active material in a well-designed photonic structure can successively reduce the active volume.Because the dimensions of the active volume are reduced to a few micrometers, spontaneous emission control can be achieved, which can provide lasing with improved directional, modal control, and reduced noise.
