The urgency of the thesis Micro- and nano-structured photonic and optoelectronic devices have been the great interests for their outstanding applications and features in integrated micro-optoelectronic circuits with high processing speed. Their unique properties have been expected to realize the new generation of opto-electronic components with high efficiency low cost and low energy consumption. 1-5 . There are two main approaches to improve the efficiency functionality and reduce the cost of photonic and opto-electronic devices i firstly of using new structures for the core elements that build up the devices ii the other approach is the use of advanced materials with many special features. Within the framework of my . thesis in materials science speciality in optical materials opto-electronics and photonics I will study in depth and present the use of new structures for photonic materials and devices which have not been available in nature for applications in telecommunication and optical processing. Photonics was appeared in the 80s of the XIX .
