Abstract: PROBLEM TO BE SOLVED: To provide a method of controlling the heat flow from a heated waveguide transferred through a substrate. SOLUTION: The optical device which is a waveguide is formed on a silicon substrate 20 and is equipped with a heating element 25 on the waveguide. The waveguide is formed on the region of a porous silicon 15 formed on the silicon substrate. The porous silicon region has higher resistance against the heat flow than that of the silicon substrate on which the device is to be formed. Optionally, the porous silicon region has higher resistance against the heat flow than that of the waveguide.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical device of a silica base on a silicon substrate. SOLUTION: This optical device has a clad layer formed within the silicon substrate. The optical device has an active region which is formed on the clad layer. The clad layer is formed by forming a region of porous silicon on the silicon substrate. The porous silicon is thereafter oxidized and is made higher in density. The active region of the optical device after the treatment to make the density higher is formed on the clad layer.

Abstract: PROBLEM TO BE SOLVED: To provide a technology by which a POWA(planar optical waveguide amplifier) is coupled to a waveguide at low loss, to provide a device comprising the POWA connected to the waveguide, and to provide a method for manufacturing such a device. SOLUTION: The planar optical waveguide amplifier comprises a first planar optical waveguide 11 and a second planar optical waveguide 12 contacting to the first planar optical waveguide. The second planar waveguide comprises a planar waveguide doped with a rare earth element, and a first tapered part 13 which connects the electromagnetic radiation of at least one specified wavelength coming from the first planar optical waveguide to the planar waveguide doped with a rare earth element.
