Abstract
Optical isolators and methods of manufacturing optical isolators are disclosed. The optical isolators are manufactured by directly bonding the parts of the isolators without the use of adhesive or mechanical devices to hold the individual parts together.
Claims34
An optical isolator comprising:
- a Faraday rotator bonded to at least one beam splitting element or polarizer to provide a bond interface, the bond being formed by an adhesive-free and epoxy-free chemical bond or vacuum bond including lithium at the bond interface.
A method of manufacturing an optical isolator comprising forming an adhesive-free and epoxy-free chemical or vacuum bond between a Faraday rotator and a beam splitting element or polarizer at a temperature below about 200° C.
A method of forming a polarization dependent isolator comprising sandwiching a Faraday rotator between a pair of polarizing glass articles, and bonding the polarizing articles to the Faraday rotator with an adhesive-free and epoxy-free process by forming chemical bonds between the Faraday rotator and the polarizing glass articles at a temperature below about 200° C. to provide an optically clear interface.
A method of forming a polarization independent optical isolator comprising sandwiching a Faraday rotator between a pair of birefringent articles and bonding the birefringent articles to the Faraday rotator with an adhesive-free and epoxy-free process by forming chemical bonds between the Faraday rotator and the birefringent articles at a temperature below about 200° C. to provide an optically clear interface.
A method of forming an optical isolator comprising bonding at least one beam splitting element or polarizer to a Faraday rotator with an adhesive-free and epoxy-free process by forming a chemical bond between the Faraday rotator and the beam splitting element or polarizer at a temperature below about 200° C. to form an optically clear interface.
