A Variable Optical Attenuation Collimator (VOAC) is disclosed to achieve a variable degree of optical power attenuation through the collimator by adding an Attenuation Control Element (ACE) between a lens element and fiber pigtails of a traditional fiber optical collimator. The body of the ACE can be implemented in many different ways such as a polymer-network liquid crystal light scattering and absorbing material, a Refraction Index Gradient Controllable Material (RIGCM) capable of controllably swerving the direction of light propagation, a Refraction Index Controllable Material (RICM) capable of controllably defocusing an incident light power and a transparent Length Controllable Material (LCM) capable of controllably changing the spacing between the lens element and the fiber pigtails causing a defocusing of an incident light power.
A multi-fiber, Variable Optical Attenuation Collimator (VOAC) for providing a variable degree of optical power attenuation to a light beam propagating therethrough, comprising:
An Attenuation Control Element (ACE) for providing a variable degree of optical power attenuation to a light beam propagating through a multi-fiber, Variable Optical Attenuation Collimator (VOAC) that comprises a lens, a pigtail and a fiber assembly containing one or more optical fibers wherein the lens and the pigtail is affixed to a common housing tube and is separated by an air in such a manner that the light beam entering at a left end of the lens is automatically focused onto a proper entry point of the pigtail for further propagation along the pigtail to the fiber assembly, the ACE comprising:
A method of making a multi-fiber, Variable Optical Attenuation Collimator (VOAC) for providing a variable degree of optical power attenuation to a light beam propagating therethrough, comprising the steps of:
