摘要： A system for monitoring an optical signal includes an optical heterodyne detection system in which an input signal and a swept local oscillator signal are combined to generate a combined optical signal. At least two beams of the combined optical signal are filtered by a filter that passes a wavelength band which tracks the wavelength of the swept local oscillator signal. As the local oscillator signal sweeps across a wavelength range, filtering of the beams is adjusted to track the wavelength of the local oscillator signal. Filtering the beams to pass a wavelength band corresponding to the wavelength of the swept local oscillator signal reduces the intensity noise contributed from light sources having wavelengths that are not near the wavelength of the local oscillator signal. Another system for monitoring an optical signal includes an optical heterodyne detection system in which the intensity noise of the input signal and/or the intensity noise of the swept local oscillator signal is reduced before the input signal and the local oscillator signal are combined. An embodiment of the optical heterodyne detection system includes an intensity noise reducer for the input signal and/or an intensity noise reducer for the swept local oscillator signal, an optical combining unit, photodetectors, and may include a processor. Utilizing intensity noise reducers for the input signal and/or the local oscillator signal reduces the intensity noise that is detected by the photodetectors and improves the signal to noise ratio of the heterodyne detection system.

摘要： An apparatus and method for measuring the thickness of a film having top and bottom surfaces. The apparatus includes low coherence light source that generates a probe light signal. The film is positioned against a roller having a partially reflecting surface that is positioned at a fixed distance from the film. The probe light signal is applied to the film and is then reflected back through the film by the partially reflecting surface. The light leaving the film is collected to form the input to a receiver that determines the time delay between light reflected from the top and bottom surfaces of the film. The receiver output may also be used to determine the thickness of the various layers in a multi-layer film.

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： A broadband tunable in-fiber filter includes a grating with divergent ridges which can be translated transversely of a side-polished optical fiber to vary the periodicity at an exposed evanescent field. The divergence is gradual so that at any given transverse position of the grating, the ridge interacting with the evanescent field are effectively parallel. The divergence is great enough so that a tuning-to-reflected bandwidth ratio of about 33:1 is demonstrated. The grating is fabricated in an amorphous silicon film on a fused quartz substrate. The film is coated with photoresist which is exposed to a holographic interference front. The substrate is tilted with respect to an interference front created by two spherically diverging beams to achieve the desired divergence. Subsequent processing, including etching are standard.

摘要： An actual optical field spectrum is mixed down to baseband and can be observed directly to measure the optical field spectrum of an optical signal based on a local oscillator approach. This local oscillator approach is achieved without adding an additional local oscillator. A single optical source, such as a laser, is controlled by a modulation source for selectively modulating the optical signal produced by the optical source. Accordingly, the optical signal produced by the optical source alternates between two states, namely, an unmodulated state and a modulated state which carries the optical field spectrum of interest. Preferably, the optical signal produced by the optical source is routed to an optical conduit in parallel with an optical delay line. Although the two states of the optical signal produced by the optical source occur sequentially in time, they are mixed together concurrently after being channeled through the parallel optical circuit comprising the optical conduit and the optical delay line. The unmodulated state of the optical signal produced by the optical source serves as a local oscillator signal. The parallel combination of the optical conduit and the optical delay line together with a photodetector functions as a self-homodyne receiver when fed the unmodulated and modulated states of the optical signal produced by the optical source. The self-homodyned mixing of the unmodulated and modulated states of the optical signal produced by the optical source serves to frequency-translate the optical power spectrum to within the bandwidth of an analyzer, such as a microwave spectrum analyzer.

摘要： Various methods and apparatuses are described in which an array of optical gain mediums capable of lasing are contained in a single integral unit. The array may contain four or more optical gain mediums capable of lasing. Each optical gain medium capable of lasing supplies a separate optical signal containing a band of wavelengths different than the other optical gain mediums capable of lasing in the array to a first multiplexer/demultiplexer. A connection for an output fiber exists to route an optical signal to and from a passive optical network.
