Abstract
A polarized light synthesizing apparatus has a lens assembly including a securing member for securing ends of a plurality of optical fibers which can propagate light having different polarization components and a lens for converting the plural kinds of polarization component light emitted from the optical fibers into collimated beams, and a birefringent member for polarization-synthesizing the plural kinds of polarization component light as the same optical axis using a difference in refractive index characteristic between the plural kinds of polarization component light emitted from the lens, thereby largely decreasing a packaging size of the apparatus while keeping functions of a known optical circuit device, a required resistance to light, reliability and readiness of fabrication.
