Abstract
An optical receiver module that provides a semiconductor optical amplifier (SOA) is disclosed. The optical receiver module provides the SOA in another housing and a photodiode (PD) enclosed in another housing. The housing for the SOA and the other housing for the PD are fixed as interposing a coupling unit therebetween, which is rigidly fixed to those housings. The coupling unit has a bore that passes light output from a facet of the SOA and received by the PD. A feature of the coupling unit is that a width or diameter of the bore of the coupling unit is smaller than widths of respective housings along a direction perpendicular to the optical axis of the light.
