摘要： An all-optical switch with wavelength conversion is disclosed. The optical switch comprises an input waveguide for carrying a multiplexed optical signal comprised of a plurality of wavelength channels. Further included is a demultiplexer for separating the multiplexed optical signal into the plurality of wavelength channels. The wavelength channels are then provided to a wavelength converter operative to convert the wavelength channels into a converted wavelength channel. The converted wavelength channels are input to a switch operative to switch the converted wavelength channels onto output waveguides.

摘要： A design technique minimizes the loss and ripple in the spectral response of an optical filter formed using a pair of gratings connected by an array of optical elements. This filter can be, for example, two waveguide grating routers (WGRs) connected by an array of waveguides. Each WGR includes two star couplers connected by waveguide grating arms. The smoothest spectral response is achieved for a given set of connecting waveguides, by choosing the number of grating arms less than or equal to filling the star coupler central Brillouin zone made by the set of connecting waveguides resulting in the connecting waveguides neither substantially over- or under-sampling the optical spectrum from the waveguide gratings. Exactly filling the Brillouin zone with the grating arms minimizes the loss, and so is the preferred choice.

摘要： A multiplexing device includes two facing-but-spaced apart optical transmitting plates, with optical reflective filters in facing contact with outer surfaces of the optical transmitting plates to define a reflective beam path therebetween. Light transceivers are associated with each of the optical reflective filters. The optical transmitting plates have greater indices of refraction than the central medium between them, so that the beam path has a low angle of incidence to the optical reflective filters but a higher angle in the central medium.

摘要： An in-line pre-compensation circuit distorts an electronic information signal prior to using the signal to modulate a laser beam in order to compensate for distortions resulting from transmitting the resulting optical signal through an optical fiber. The pre-compensation circuit is dynamically adjustable for different lengths of optical fiber for simple installation and maintenance of the system. The adjustment can be made from a front panel of a laser transmitter during operation. Even though the optical signal is more distorted at the output of the laser transmitter, the optical signal that arrives at the receiver is less distorted.
