摘要： An apparatus and method for measuring the thickness of a film having top and bottom surfaces. The apparatus includes a first coupler for generating a first probe light signal and a second probe light signal from a low coherence light source. The first probe light signal is directed toward the top surface of the film and the light leaving the top surface of the film is collected. Similarly, the second probe light signal is directed toward the bottom surface of the film and the light leaving the bottom surface of the film is also collected. Top and bottom partially reflecting reference surfaces are provided for generating reflections. The top reference surface reflects part of the light leaving the top surface back toward the top surface, and the bottom reference surface reflects light leaving the bottom surface of the film back toward the bottom surface of the film. The collected light is combined to form a collected light signal which is input to a receiver that determines the time delay between light reflected from the top surface of the film and the top reference surface and between the bottom surface of the film and the bottom reference surface. In the preferred embodiment of the present invention, the receiver is constructed from an optical autocorrelator or an optical spectrum analyzer that includes circuitry for providing the Fourier transform of the frequency domain spectrum measured from the collected light signal.

摘要： An optical switch includes a pump source, a pump director, and a pump-dependent attenuator. The pump-dependent attenuator passes optical signals when it is supplied with pump energy at a pumping wavelength and attenuates optical signals when it is not supplied with pump energy. The pump source generates pump energy for the pump-dependent attenuator, and the pump director optically manipulates the delivery of pump energy to the pump-dependent attenuator. In a preferred embodiment, the pump-dependent attenuator is an erbium-doped fiber (EDF), the pump source is a laser diode, and the pump director is a tunable fiber Bragg grating (FBG). The EDF is located along an optical signal transmission path between an input waveguide and an output waveguide. The tunable FBG is located along a transmission path between the laser diode and the EDF. To operate the switch, pump energy at a pumping wavelength is generated by the laser diode and transmitted toward the tunable FBG. To turn on the switch, the FBG is tuned off of the pumping wavelength of the EDF, thereby passing pump energy to the EDF, and to turn off the switch, the FBG is tuned onto the pumping wavelength of the EDF, thereby blocking pump energy to the EDF. An adjustable bandpass filter may also be used as the pump director. The optical switch can also be applied to various optical systems, such as a 1.times.N switch, add/drop multiplexers, broadcast/multicast switches, and wavelength-selectable lasers.

摘要： Wavelength division multiplexing (“WDM”) passive optical networks (“PON”) to transport signals having various access platforms are described. For one embodiment, a WDM PON performs bi-directional communications, and includes an interface. The interface transfers one or more signals having a first platform to a WDM-PON data transmission platform at an access point of a network to propagate through a single transmission medium, to one or more remote distribution nodes in between a Central Office and an optical network unit. The single transmission medium carries three or more optical channels traveling in both directions.
