Abstract: [cze] [eng]
Navrhli jsme a experimentálně ověřili použití optické vláknové mřížky s dlouhou periodou pro konverzi fázové modulace na amplitudovou. Aplikovali jsme ji na místo diferenciálního interferometru ve vlnovém konvertoru založeném na křížové fázové modulaci a následně využili ke konverzi signálu z 1572nm na 1555nm při 160Gb/s. We proposed and demonstrated that long-period fiber grating can serve as converter of phase modulation to amplitude modulation in wavelength converters based on XPM. In our particular implementation, an input pulse train with repetition rate of 160Gb/s at the wavelength of 1572nm were converted to train of 2ps pulses at 1555nm. We shown its benefits compared to differential interferometric schemes used for the same purpose.
