Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus which enable the development of a simple and inexpensive device for providing the wavelength conversion of an optical communication signal and 3R (re-amplification, re-timing, and re-shaping) optical signal regeneration. SOLUTION: The method and the apparatus for providing optical 3R regeneration include 1) generating an encoded optical clock signal from at least an optical signal, 2) introducing the encoded clock signal into a delay interference section of a regenerator so as to produce an amplitude modulated clock signal, and outputting the amplitude modulated clock signal. The outputted amplitude modulated clock signal preserves information present within the input optical signal.

Abstract: PROBLEM TO BE SOLVED: To provide a wavelength converter which is provided with monolithically integrated delay loops existing in a delay interference constitution having only a solitary SOA(semiconductor optical amplifier). SOLUTION: This wavelength converter is different from the conventional hybrid wavelength converter and has monolithically integrated delay loops which use an asymmetric separation coupler 130.

Abstract: PROBLEM TO BE SOLVED: To provide an all-optical wavelength converter/regenerator which can completely separate an input signal from an output signal. SOLUTION: The delay interference all-optical wavelength converter converts a pulsed input signal Pin at a wavelength λ1 into a wavelength converted signal Pconv at a wavelength λ2 . The wavelength of the input signal and the wavelength of the converted signal may be different from each other or the same. The converter has an input signal coupling unit for receiving the pulsed input signal and supplying it to one input of a modulation section. A carrier signal Pcw is supplied to the other input of the modulation section. The output of the modulation section Pint is supplied to a delay-interference section. The delay- interference part converts the Pint into a primarily amplitude-modulated signal. A wavelength filtering element or device which can achieve partial or complete input-signal wavelength filtering, is either a part of the modulation section, a coupling unit, the delay-interference section or an integral part of the whole configuration.

Abstract: PROBLEM TO BE SOLVED: To provide a broadband wave division multiplexer/demultiplexer having an input from different wavelength bands. SOLUTION: An example of embodiment of the device is the broad band wave division multiplexer having two input waveguides 102 and 103 for two input signals from different wavelength bands, an MMI waveguide 104 which generates an output WDM(wave division multiplexing) signal from two input signals, and a WDM output waveguide 105 which combines the output WDM signal. As an option, at least a separate output waveguide 106 is used for trapping all powers which are not coupled for generating the output WDM signal or a part of powers.

Abstract: A delayed interference all-optical wavelength converter is arranged to convert and reshape a pulsed input signal P in at .lambda.1 into the wavelength converted signal P conv at .lambda.2, where .lambda.1 and .lambda .2 are different. A delayed interference all-optical wavelength regenerator is similar, but is arranged to reshape a pulsed input signal P in into the wavelength converted signal P conv, where the wavelengths of the input signal and the converted signal are the same. The converter/regenerator comprises an input-signal coupling unit for receiving the pulsed input signal and supplying it to one input of a modulation section, the other input to which is a carrier signal P cw. The output of the modulation section P int, which is generally speaking, a phase modulated signal which may also have an amplitude modulated component, is applied to a delay interference section arranged to transform P int into a primarily amplitude-modulated signal. A wavelength filtering element that ca n enable partial or even complete input-signal wavelength filtering, is either a part of the modulation section, the coupling unit, the delay-interference section or an integral part of the whole configuration.
