An Analysis of FSK Transmission Characteristics of Spectrum Sliced Optical Signals

Spectrum-Sliced WDM Using FSK Transmission

The focus of this chapter is to consider the case of spectral-slicing when Frequency-Shift Keying (FSK) is used as the modulation scheme. Although the majority of lightwave systems use conventional On-Off Keying (OOK) or intensity modulation, FSK is preferred in certain situations and this chapter will discuss where transmission using FSK may prove advantageous in the context of a noise-like sp...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Spectrum-Sliced WDM Using OOK Transmission

This chapter presents one of the primary contributions of this dissertation: a mathematical model to analyze and evaluate noise-like spectrum-sliced systems which employ conventional PIN receivers, or as proposed in this dissertation, optical preamplifier receivers. As discussed in previous chapters, spectrum-slicing provides a low-cost alternative to the use of multiple coherent lasers for WDM...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
