  • Patent number: 10598857
    Abstract: A pin hole or aperture is located or formed adjacent to the end surface of one or more of the input ports or fibers, or adjacent to one or more of the output ports or fibers, of a fiberoptic component. The aperture allows light to enter (or exit) the core of the associated fiber, and the non-transparent layer that surrounds the aperture blocks light from entering or exiting the cladding layer of the associated fiber. This blocking of the evanescent field in the cladding layer serves to reduce the polarization, wavelength, and temperature dependencies of the light coupling to the output port(s) or fiber(s) of the optical component. It can also reduce the passband width of the selected wavelength in tunable optical filter applications. The non-transparent layer surrounding the aperture can be made reflective, and light that is reflected by the non-transparent layer can be used for optical power monitoring.

  • Patent number: 9660681
    Abstract: Light of at least two wavelengths is collimated in a forward path towards a reflector and light of at least one of the wavelengths is focused and detected in a return path, using in both paths a lens unit including a first convex surface and a second surface. A diffraction element diffracts the collimated light of the at least two wavelengths into different wavelength components. The reflector is moved so that one or more of the different wavelength components will be focused by the lens unit in the return path and detected. The second surface reflects the light of the at least two wavelengths from an input port towards the first convex surface and the first convex surface collimates the reflected light of the at least two wavelengths in the forward path, or the first convex surface focuses the one or more wavelength components towards the second surface that reflects the one or more wavelength components to an output port in the return path.

  • Patent number: 6975678
    Abstract: An adaptive equalizer system and method uses an averaging algorithm to adjust equalization and amplitude for a data signal. Two sampled data points, spanning a sampling window, are obtained from the equalized signal. The data points are evaluated to determine when a signal condition persists long enough to require equalization adjustment, as well as evaluating persistent conditions in the amplitude of the received data signal. By monitoring persistent conditions in the equalized signal, the average signal received by the equalizer is compensated. The bit resolution of the equalizer control and the amplitude control can be selected for a desired resolution in a system. The incoming data signal is used to generate the requisite timing signals for sampling and control such that high frequency clock circuits and PLL techniques are unnecessary resulting in lower power consumption and reduced costs.

  • Patent number: 6880099
    Abstract: An input signal with an associated pulse width can be sampled using a sampling method that does not require a clock signal. The input signal is compared to a reference level signal to produce a comparator output signal. Strobe signals are generated from the input signal, where the strobe signals occur within a pulse width of the input signal. Sampled data points are generated in response to the comparator output signal and the strobe signals such that the sampled data points are within the pulse-width of the input signal. One of the strobe signals may be used to periodically reset the comparator. The sampling logic circuit may be constructed from common logic gates and memory circuits such as flip-flops. In one example application the sampling method is applied to an equalizer system. The equalizer system includes an equalizer circuit that produces an equalized signal. A data slicer circuit converts the equalized signal into a digital representation.
