Abstract
Disclosed is a waveguide polarizing optical device, including a first waveguide polarizer (6), a section of a second optical waveguide (31) and a second thin-plate polarizer (52) having a physical thickness T and a refractive index n, the second thin-plate polarizer (52) being disposed on the optical path between a waveguide end (8) of the first polarizer (6) and one end (32) of the second optical waveguide (31), the physical distance d between the waveguide end (8) of the first polarizer (6) and the end (32) of the second optical waveguide (31) being less than or equal to twice the Rayleigh length and the physical thickness T of the second polarizer (52) being less than or equal to the physical distance d.
