A broadband interconnection device ( ) used for interconnection between a first transmission line ( ) and a second transmission line ( ), has a substrate ( ) with the first transmission line ( ) defined at a first side ( ) on a first surface ( ), the first transmission line ( ) including a signal conductor ( ) and at least one ground conductor ( or ), a signal conductor ( ) of the second transmission line ( ) defined on an opposite side ( ) of the first surface ( ), and a ground plane ( ) of the second transmission line ( ) on an opposed surface ( ), the signal conductor ( ) of the first transmission line ( ) being electrically connected to the signal conductor ( ) of the second transmission line ( ) on the first surface ( ). On the opposed surface ( ), the ground plane ( ) of the second transmission line ( ), has at least one protrusion ( ) aligned with the signal conductor ( ) of the first transmission line ( ).

Broadband uniplanar coplanar transition

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.
