Patent ID: 7824111

Claim:
An optical module comprising: a substrate having a substrate surface provided with terminal pads and landing pads; and an optical element package having a top surface, a bottom surface and terminals, and mounted on the substrate surface with a gap formed between the bottom surface and the substrate surface, wherein the gap is determined by the landing pads when the optical element package is mounted on the substrate surface, in a plan view from above the substrate surface and viewed perpendicularly to the substrate surface, the terminal pads are partially exposed with respect to the optical element package in a state where the optical element package is mounted on the substrate surface, a plurality of recesses are provided in a side surface of the optical element package, said side surface extending from the bottom surface towards the top surface of the optical element package, the terminals of the optical element package are provided within the recesses, the recesses face the terminal pads in a state where the optical element package is mounted on the substrate surface, the terminal pads are electrically connected to corresponding terminals by solder, and the solder extends between the exposed terminal pads and the corresponding recesses.
