80-Gb/s wavelength conversion based on cross-phase modulation in high-nonlinearity dispersion-shifted fiber and optical filtering

Abstract

Abstract-Using cross-phase modulation in a 1-km high-nonlinearity dispersion-shifted fiber with subsequently filtering by a tunable optical filter, 80-Gb/s pulsewidth maintained wavelength conversion is realized. Penalty-free transmission over 80-km conventional single-mode fiber and 12-km dispersion-compensating fiber for 80-Gb/s converted signal is realized.Index Terms-High-nonlinearity fiber, nonlinear optical loop mirror, optical time division multiplexing, wavelength conversion.

All-optical devices and signal processing for all photonic network

“…Unlike electrical 3R transponders (Optical-Electrical-Optical conversion), all-optical regenerators (OpticalOptical conversion) are likely to be less complex and require fewer high-speed opto-electronic and electronic components since they use optical signal processing, which leads to a small footprint and low power consumption, even if they operate at high bit rate. So far, various types of all optical switching devices utilizing optical nonlinearity of fibers [1][2][3][4][5], semiconductor optical amplifiers (SOAs) [6][7][8][9][10][11], and electro-absorption modulators (EAMs) [12][13][14][15][16][17][18][19]. Alloptical regeneration performance depends on the physics of each optical nonlinearity, which has a respective trade-off between the switching speed and the required optical power for switching.…”
