Abstract: A broadband interconnection device (10) used for interconnection between a first transmission line (100) and a second transmission line (200), has a substrate (300) with the first transmission line (100) defined at a first side (310) on a first surface (320), the first transmission line (100) including a signal conductor (120) and at least one ground conductor (121 or 122), a signal conductor (220) of the second transmission line (200) defined on an opposite side (340) of the first surface (310), and a ground plane (260) of the second transmission line (200) on an opposed surface (360), the signal conductor (120) of the first transmission line (100) being electrically connected to the signal conductor (220) of the second transmission line (200) on the first surface (320). On the opposed surface (360), the ground plane (260) of the second transmission line (200), has at least one protrusion (261) aligned with the signal conductor (120) of the first transmission line (100).

Abstract: An optical device for detecting chromatic dispersion is described. The optical device includes a receiver, which converts an optical signal into an electrical signal having a plurality of frequency components. A bandpass section separates the plurality of frequency components and a gain section amplifies each of the plurality of frequency components of the electrical signal. Each of the spectral components has a corresponding voltage level and each voltage level may be compared to known voltage levels of a signal having little or no chromatic dispersion. From this comparison, the amount of chromatic dispersion may be determined. The optical device may be used as an element of a chromatic dispersion compensation device, or as a stand-alone device for measuring the amount of chromatic dispersion in an optical signal. A method of compensating for chromatic dispersion in real-time based on the optical device and dispersion compensator is also described.
