Example implementations described herein are directed to a system involving one or more photonic integrated circuits having multi-mode waveguides and connected to a printed optical board through the use of multi-mode waveguide connectors described herein. The printed optical board can include an embedded multi-mode waveguide bus to facilitate optical signal to and from the photonic integrated circuits. The system can also include a chiplet such as a photonic integrated circuit with a single mode waveguide configured to connect to an optical fiber cable.

First terminals have a contact arm portion and second terminals have a convex contact point portion that is contactable with the intermediate portion of the contact arm portion of the first terminals in the direction of plugging and unplugging of the two connectors. The section of the contact arm portion of the first terminals that extends from the location of contact with the convex contact point portion of the second terminals to the free end portion of the contact arm portion in the direction of plugging and unplugging forms a stub portion. The sections of the first terminals other than the stub portion and the second terminals constitute a main transmission path. In a predetermined range that includes the location of contact in the main transmission path, the impedance of at least a partial range of said predetermined range is made smaller than the impedance of the stub portion.

Electrical connector assembly

The first terminals have contact arm portions extending in a rectilinear manner in the direction of connector plugging and unplugging; the second terminals have convex contact point portions contactable with an intermediate portion of the contact arm portions in the same direction. When the stub portions of the contact arm portions are divided into a free end side range and a proximal end side range such that the center point of said stub portions in the direction of plugging and unplugging forms a boundary, in the arranged state of the first terminals, impedance at arbitrary locations in the direction of plugging and unplugging within the free end side range is larger than impedance at arbitrary locations in the plugging direction within the proximal end side range.
