Abstract: To provide economical high-speed optical communications through an optical module a silicon substrate with a ball lens and semiconductor luminescence element mounted thereon, and a laser driver IC are provided. A silicon subassembly includes a silicon substrate with a pyramidal cavity etched into the substrate near its edge. A ball lens is precision-mounted in the pyramidal cavity by bonding it at multiple points. This provides a high-strength connection and a small, inexpensive silicon substrate. Also provided on the silicon substrate is a semiconductor luminescence element and a slit on the opposite side of the ball lens. The slit enables collimated light emitted from the ball lens to be optically coupled without being blocked or reflected by the substrate. The semiconductor luminescence element and its laser driver IC are placed in close proximity to each other, and ribbon wires are kept short (approximately 300 &mgr;m) to reduce signal line impedance mismatch for high-speed transmission.

Abstract: A photodetector module that can achieve impedance matching and power saving. A photodetector (11) and an amplifier (12) for amplifying an electric signal from the photodetector (11) are mounted on a stem (14). A dielectric plate (18) is arranged between the stem (14) and a flexible substrate (20). To transfer an electric signal from the amplifier (12) to the substrate (20), a lead pin (15d) is provided to pass through the stem (14) and the dielectric plate (18). The output of the amplifier (12) includes a capacitance component, and the output impedance of the amplifier (12) is higher than the impedance that matches with the substrate (20). Further, the thickness d of the dielectric plate (18) is such that the inductance component of the lead pin (15d) includes an inductance component that is inductive, which cancels the capacitance component of the amplifier, and impedance matching with the substrate (20) can be achieved.
