Abstract:
An optical module includes a single-mode optical fiber; a high relative refractive-index difference optical fiber having a larger core-to-cladding relative refractive-index difference than that of the single-mode optical fiber fusion-spliced to a first end of the high relative refractive-index difference optical fiber; a planar lightwave circuit that includes an optical waveguide having a core of quartz-based glass doped with a refractive-index raising dopant and a cladding of quartz-based glass, and is connected at a first end thereof to a second end, opposite to the first end, of the high relative refractive-index difference optical fiber; and a silicon thin-wire waveguide element that includes a silicon thin-wire waveguide having a silicon core and a cladding whose refractive index lower than that of the silicon core, and is connected to a second end, opposite to the first end, of the optical waveguide of the planar lightwave circuit.

Claim (Index 1):
An optical module comprising:\n a single-mode optical fiber; a high relative refractive-index difference optical fiber having a larger relative refractive-index difference of a first core with respect to a first cladding than a relative refractive-index difference in the single-mode optical fiber, wherein the high relative refractive-index optical fiber is fusion-spliced at a first end surface thereof to the single-mode optical fiber; a planar lightwave circuit including an optical waveguide having a second core formed of quartz-based glass doped with a refractive index raising dopant and a second cladding formed of quartz-based glass, thereby to guide light through the second core, wherein the optical waveguide is optically connected at a first end thereof to a second end surface of the high relative refractive-index difference optical fiber, the second end surface being opposite to the first end surface of the relative refractive-index difference optical fiber; and a silicon thin-wire waveguide element including a silicon thin-wire waveguide having a third core formed of silicon and a third cladding having a refractive index lower than the refractive index of the third core, thereby to guide light through the third core, wherein the silicon thin-wire waveguide is optically connected to a second end surface of the optical waveguide of the planar lightwave circuit, the second end surface being opposite to the first end surface of the optical waveguide of the planar lightwave circuit.
