WAVELENGTH CONVERTER FOR PROCESSING HIGH-SPEED OPTICAL SIGNAL

摘要

PURPOSE: A wavelength converter for processing a high-speed optical signal is provided to process the high-speed optical signal by using a semiconductor optical amplifier as a laser gainer. CONSTITUTION: An optical attenuator(120) is used for attenuating an optical output of an optical fiber. The first and the second polarization controllers(140,260) are used for controlling a state of polarization. A 3-db optical fiber coupler(160) is used for dividing optical intensity into 50 to 50. An optical isolator(180) is used for transmitting an optical wavelength of the optical fiber. A semiconductor optical amplifier(200) is used for amplifying an optical wavelength of a semiconductor optical fiber. A turnable coupler(220) is used for varying and coupling output intensity of the optical fiber. A wavelength varying broad band pass filer(240) is used for varying and filtering the optical wavelength of the optical fiber.
