Abstract
An optical module includes a package, which accommodates an optical system. A package main body has an opening. A lid is attached to the main body to close the opening of the main body. The lid seals the package. An anti-deterioration agent for preventing deterioration of the optical system is located inside the package at a position out of a light path of the optical system. The anti-deterioration agent includes at least one of desiccant and deoxidant.

An optical module, wherein the optical module includes a package that accommodates an optical system having a light path, the optical module comprising;
- a main body, which is part of the package, wherein the main body has an opening;
- a lid, which is attached to the main body to close the opening of the main body, wherein the lid seals the package;
- and
- an anti-deterioration agent located inside the package at a position out of said light path of the optical system, wherein said anti-deterioration agent is for preventing deterioration of the optical system, wherein the anti-deterioration agent includes at least one of desiccant and deoxidant.
An optical module, wherein the optical module includes a package, which accommodates an optical system, the optical module comprising;
- a main body, which is part of the package, wherein the main body has an opening;
- a lid, which is attached to the main body to close the opening of the main body, wherein the lid seals the package;
- and
- an anti-deterioration agent located inside the package at a position out of a light path of the optical system for preventing deterioration of the optical system, wherein the anti-deterioration agent includes a first molded piece, which is formed into a sheet, and a second molded piece, which is formed into a block,
- wherein the optical system includes a collimator lens and a diffraction grating, wherein the collimator lens converts incident light, which consists of optical signals, into parallel light, and wherein the diffraction grating separates the parallel light into optical signals having different wavelengths, and
- wherein the first molded piece is located along the inner surface of the main body, and the second molded piece is located at the rear of the diffraction grating.
