Abstract:
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.
Abstract:
The connector has multiple connection elements arranged on a circuit board and supports which support the connection elements. The connection elements have terminals connected to counterpart terminals in a counterpart connector, as well as stationary retainers and movable retainers that secure the terminals in place. The terminals have connecting portions at one end of the terminals, and contact portions at the other end, and the contact portions are secured in place on one side of the movable retainers. Flexible portions are formed between the movable retainers and the stationary retainers. The movable retainers are provided with biasing members on the other side opposite to the side on which the contact portions are positioned.

An electrical connector includes connecting members arranged in an arrangement direction; and a housing member for accommodating the connecting members. The connecting member includes a terminal connected to the mating connector, and a holding member for holding the terminal. The terminals includes a connecting portion at one end in a longitudinal direction for connecting to a circuit portion of the circuit board, a contact portion at the other end in the longitudinal direction for contacting with a mating contact of the mating connector, and a held portion near the connecting portion in the longitudinal direction and held with the holding member. The housing member is be movable linearly or rotatable relative to the holding member. The housing member includes a guiding surface for guiding the mating terminal. The terminal includes a deformable portion opposite to the connecting portion. The deformable portion deforms when the guiding surface guides the mating terminal.

Abstract:
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.
