Abstract

Using a unique polarization-maintaining (PM), low-birefringence (low-bi) fiber, we demonstrate a low-latency soliton logic gate in a 15-m fiber with a switching energy of 93 pJ and contrast ratio of 2.73. We drive the logic gate by using the amplified output from a passively-mode-locked color-center laser (CCL) or an erbium-doped fiber laser (EDFL) that delivers 0.5-ps pulses with ~40 pJ/pulse. This all-fiber integration of laser, amplifier, and logic gate is an important step toward practical applications in high-speed all-optical networks.
