There are provided a power supply device for an optical functional component that supplies power to the optical functional component with reliability for a long term and enables easy exchange of the optical functional component, and an optical functional module having such a power supply device, where the power supply device is provided with a reception electrode, a power supply electrode-that supplies power to the reception electrodewhile holding tight the reception electrodeon its side faces and thereby holding an optical functional component-detachably, and a protecting memberthat is made of an insulating material and surrounds the power supply electrode-to prevent current leaks, and the power supply electrode-is comprised of two bent metallic members (-and-B) which are in intimate contact with the reception electrodeby elasticity.

Functional optical module

The invention comprises three parts: The first parts provides a miniaturized functional optical module, which is provided with a lens-exchange type collimator enabling rapid and easy exchange of an optical functional component and/or lenses and being compact in size and excellent in durability. The second part provides a power supply device for an optical functional component that supplies power to the optical functional component with reliability for a long term and enables easy exchange of the optical functional component, and an optical functional module having such a power supply device. The third part provides an optical switch compact in size and greatly easy in handling, which is provided with a connector module having a plurality of optical fibers for light-beam input, a plurality of optical fibers for light-beam output corresponding to the plurality of optical fibers and a light-beam reflecting member.

This invention relates to a method for tuning optical characteristic of an optical module. The tuning method in optical characteristic of an optical module consisting of an optical fiber, a lens, an optical filter and a filter holder, comprising: a step of tuning an optical characteristic to turn the optical filter or the said optical fiber around the axis offset from the center of the said optical filter.
