摘要:
The present invention provides a light generation method and a light source that are preferable in obtaining a single-mode light having high outputs, a small wavelength spectral bandwidth, and a low intensity noise. A white output from a white-light source and having wavelength components over a wide-band in a wavelength spectrum passes through an isolator and is then filtered by a disc-shaped optical filter. A transmitted light is input to a semiconductor optical amplifier having its polarization plane regulated by a polarization controller. An output from the amplifier passes through an isolator and is then filtered by a disc-shaped optical filter again to generate a single-mode light having a small spectral bandwidth and high outputs. Polarization control by the polarization controller corresponds to control of the polarization plane of a semiconductor laser in the semiconductor optical amplifier so as to obtain a maximum gain from the amplifier. This configuration enables a single-mode light having a small spectral bandwidth and high outputs to be easily generated at an arbitrary wavelength.

A disk shaped tunable optical filter is formed by a transparent substrate in a disk shape, and a filter layer formed on a top surface of the substrate, having such a filter characteristic that a transmission central wavelength varies along a circumferential direction as a monotonic function of a viewing angle. This disk shaped tunable optical filter can be advatageously utilized in realizing a wavelength discrimination apparatus, a reference wavelength light generation apparatus, an optical packet generation apparatus, and a tunable optical filter module, which are also disclosed.

A conductive film comprises a phosphide particle coated film formed by attaching raw material particles including phosphide particles comprising a compound of Ti and/or Fe, and P to a surface of a substrate material. This conductive film exhibits good corrosion resistant conductivity, and can be easily formed at low costs because of comprising the phosphide particle coated film. A corrosion-resistant conduction film comprises an iron-containing titanium phosphide layer containing Ti, Fe and P as essential basic elements. A corrosion-resistant conduction material having this corrosion-resistant conduction film on a surface of a substrate exhibits good corrosion resistance or conductivity. This corrosion-resistant conduction material can be obtained, for example, by a process comprising a plating step of forming an Ni plating layer on a surface of a Ti-based material substrate and a nitriding step of applying nitriding treatment to the Ti-based material substrate after the plating step at not more than 880 deg. C.
