In an optical connector adapter for use in connecting first and second optical connectors to each other, the optical connector adapter includes a shell member which has a wall portion defining an opening and which receives the first optical connector. The die has a plurality of peripheral bond pads along a periphery of the die and a first bond pad on an interior portion of the die wherein the first bond pad is a power supply bond pad. Also, the video output system may further comprise a generator locking device or the video input module may include a generator locking device. The shell portion has two gas inlet orifices, one on each side of the median place. In another aspect, silicon slot waveguides that exhibits four zero-dispersion wavelengths with a flattened dispersion over a wavelength range of 670-nm are obtained.
