摘要： PROBLEM TO BE SOLVED: To compensate the temperature dependence of EDFA in a 1525 to 1565 wavelength range and to realize wavelength multiplexed transmission. SOLUTION: First and second long-period gratings having different grating periods are formed in an optical fiber in such a manner that the peak wavelength in the curve of the optical transmission loss characteristics in the first long-period grating side is formed in the shorter wavelength side than the transmission band as shown in Fig 1 (a) and that the peak wavelength in the curve of the optical transmittance loss characteristics in the second long-period grating side is formed in the longer wavelength side in the transmission band as shown in Fig 1 (b). When the curves of the optical transmission loss characteristics are shifted depending on the temperature, the optical transmission loss in the short wavelength side of the transmission band is increased with the increase of the temperature by the loss deviation characteristics of the first long-period grating to compensate the large gain deflection characteristics of an optical amplifier, while the residual gain deviation characteristics in the long wavelength side in the transmission band are compensated by the loss deviation characteristics of the second long-period grating. Thus, the gain temperature characteristics in the transmission band of the optical amplifier are compensated.

摘要： PROBLEM TO BE SOLVED: To manufacture an optical filter having accurate optical film thickness by accurately controlling the optical film thickness of films deposited on a substrate. SOLUTION: While a film 4 is deposited on a substrate 3, at least one of the optical characteristics of energy transmittance and energy reflectance when a film deposited on the substrate 3 is irradiated with monitor light is represented by f (t) as a function of time t with a theoretical constant ak (k is an integer >=0) based on the theoretical formulae of optical characteristics, wherein the time t represents the film deposition period from the preliminarily determined referential time. During the film 4 is deposited, the real optical characteristics are occasionally measured by irradiating the film 4 with the monitor light at time t, and the theoretical constant ak is corrected to obtain a proper constant ak' so as to minimize the difference between the measured value and the theoretical value of the optical characteristics calculated from the function f (t). The time of reaching the determined film thickness when the optical film thickness of the deposited film 4 reaches the preliminarily determined thickness is predicted based on the proper constant ak', and the film deposition is stopped at the time of reaching the determined film thickness to obtain the optical filter.

摘要： PROBLEM TO BE SOLVED: To exactly control the optical film thickness of a film to be deposited on a substrate for a product, and to manufacture an optical filter having an exact optical film thickness. SOLUTION: The related data between the optical film thickness of the film to be deposited on a monitor substrate 2 and the reflectivity of the film are obtained previously for each film material, and are set as thickness control data. The data of the correction factor for correcting the deviation between the optical film thickness of the film to be deposited on the monitor substrate 2 and the optical film thickness to be deposited on the substrate 3 for a product are previously obtained for each film material in correspondence with the wavelength of monitor light when the substrate 3 for a product and the monitor substrate 2 are placed in a film deposition area 7, respectively and film deposition is performed simultaneously on the substrates, and the data are sets as data for film thickness correction factor. When performing the film deposition of the film for a product on the substrate 3 for a product, the reflectivity of the film on the monitor substrate 2 is measured by performing the film deposition simultaneously also on the monitor substrate 2. The film deposition is stopped when a measured value reaches the reflectivity of the thickness control data corresponding to the optical film thickness corrected with the data for film thickness correction factor.
