Development of optical multi-channel connector for rigid waveguide — Fiber optical interconnection

We propose a newly developed optical multi-channel connector to connect a rigid optical waveguide array and an optical fiber array for an on-board optical interconnection. The prototype of a 24-channel optical card edge connector to connect between a rigid multimode waveguide array fabricated onto a substrate and a multi-mode fiber array is manufactured, and two types of optical connection losses are defined and evaluated by the direction of the optical signal. The optical connection losses from the waveguide to the fiber as transmitting function and from the fiber to the waveguide as receiving function, are less than 0.7 dB and 0.6 dB, respectively.
