Abstract

The core adjusting process includes a procedure of searching for the position in which the photocurrent of the light-receiving element reaches its peak in each of the X-, Y-, and Z-directions. In the searching procedure, the light emitted from a multimode fiber of a MCP is gathered by a lens and is transmitted to the light-receiving element. A check is then made to determine whether, at in both directions of the search direction, there exist a first and second attenuation positions in which the photocurrent shows a predetermined attenuation relative to a peak value in a search range. If there exist the attenuation positions, a peak position is determined to be a position located within a second predetermined range from the middle point between the attenuation positions, and the relative positions of the receptacle and the CAN package are adjusted to the peak position.

Description

[0001] Cross References to Related Applications [0002] This application is based on Japanese Patent Application No. 2009-130090, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a method of manufacturing an optical receiver module and a device for manufacturing an optical receiver module. Background technique [0004] First, a general structure of a semiconductor optical receiver module (optical receiver module) including a planar light receiving element (photodiode (PD)) is described. [0005] An optical receiver module including a planar light receiving element includes a stem, a carrier on the stem, and a planar light receiving element on the carrier. Carriers and light receiving elements, transimpedance amplifiers (TIA), capacitors for noise reduction, etc. can also be mounted on the header. The optical receiver module further includes a cap (such as a flat window cap with a flat window) that hermeti...
