Summary:PROBLEM TO BE SOLVED: To provide an optical module and an optical transmission method capable of easily and flexibly preventing displacement of a convergent point.SOLUTION: An optical module 100 includes: a lens 2; a lens cap 3; and a transmission member 7. The lens 2 focuses a laser beam emitted from a semiconductor laser 1 to a convergent point. The lens cap 3 supports the lens 2. The transmission member 7 is fixed to the lens cap 3 so that an asymmetric stress is applied to the transmission member 7 around the optical axis of the lens 2. The transmission member 7 is disposed on an optical path. 【課題】より簡便かつ柔軟に集束点の位置ずれを抑制する光モジュール及び光伝送方法を提供する。【解決手段】光モジュール１００は、レンズ２と、レンズキャップ３と、透過部材７とを備える。レンズ２は、半導体レーザ１から出射されるレーザ光を、集束点に集束させる。レンズキャップ３は、レンズ２を支持する。透過部材７は、レンズ２の光軸を中心として非対称な応力が熱膨張に応じて加わるようにレンズキャップ３に固定される。透過部材７は、光路上に配置される。【選択図】図１
