LIGHT POLARIZER, LIGHT POLARIZER MANUFACTURING METHOD, AND OPTICAL ISOLATOR

PROBLEM TO BE SOLVED: To provide a polarizer in which unevenness of polarizing axes of metal particles is easily suppressed, a manufacturing method thereof, and an optical isolator capable of simplifying an alignment step and improving a contrast ratio by incorporating the polarizer thereto. SOLUTION: When a polarized glass base material containing slender metal particles, the metal particles showing inclinations of polarizing axes, is prepared, a plurality of polarizer chip base materials is cut from the polarized glass base material, and a number of polarizers is further cut from the polarizer chip base material, and a side surface that is a light-impermeable surface of each individual polarizer chip base material is cut along the inclination direction of polarization axes of the polarized glass base material. Furthermore, the polarizer is disposed on each of light incident and outgoing surfaces of a Faraday rotator, thereby the optical isolator is constituted. COPYRIGHT: (C)2009,JPO&INPIT
