Abstract: An optically connectable circuit board and optical components mounted thereon. At least one component includes optical transceivers and provides an optical connection to the board. Electronic components may be directly connected to the board electrically or optically. Also, some electronic components may be indirectly connected optically to the board through intermediate optical components.

Abstract: A high speed optical channel including an optical driver and a photodetector in a CMOS photoreceiver. The optical channel driver includes a FET driver circuit driving a passive element (e.g., an integrated loop inductor) and a vertical cavity surface emitting laser (VCSEL) diode. The VCSEL diode is biased by a bias supply. The integrated loop inductor may be integrated in CMOS technology and on the same IC chip as either/both of the FET driver and the VCSEL diode. The photodetector is in a semiconductor (silicon) layer that may be on an insulator layer, i.e., SOI. One or more ultrathin metal electrodes (<2000 ?) on the silicon layer forms a Schottky barrier diode junction which in turn forms a quantum well containing a two dimensional electron gas between the ultrathin metal electrode and the Schottky barrier diode junction.

Abstract: An apparatus and method for forming a staircase arrangement for the connection of optical waveguides between a card and backplane. A card having optical waveguides and electrical conductors embedded in the card has an edge ending in a staircase arrangement with optical fiber-ribbons protruding from the edge. A guidance structure is connected to the edge and contains channels to guide and align the optical fiber-ribbons. A backplane having embedded optical waveguides and electrical conductors also has an edge ending in a staircase arrangement with a guidance structure connected to the edge and tapered openings which receive and guide the optical fiber-ribbons into close proximity with the optical waveguides and forming a staircase arrangement of connected waveguides between a card and backplane.
