摘要： In an SOA array optical module, the central axis of a beam output from each intra-SOA waveguide is oblique by 22.3 degrees to a normal to an end face of an SOA array on the output side (the same applies to the input side) of the SOA array having intra-SOA waveguides of 8 channels. First and second lens arrays are arranged for the SOA array so that the central axis of the beam that is output obliquely by 22.3 degrees from the SOA array, the optical axis of a lens convex part of each channel of the first lens array, and the optical axis of a lens convex part of each channel of the second lens array agree with one another. Level differences are provided respectively on faces opposite to the lens convex parts of the first and the second lens arrays.

摘要： In an optical module, an optical element array is an array of optical elements. Further, a lens array is an array of a plurality of lenses. An output point of a light beam of each optical element of the optical element array is caused to coincide with a central line of a corresponding lens of the lens array, and the light beam is made incident on the lens and a parallel beam is output from the lens. When the output point of the light beam of the optical element coincides with an optical axis of the lens, an optical path within the optical element and the optical axis of the lens fail to coincide with each other.
