Abstract(in Japanese) (See Japanese page)
Abstract(in English) Control of temperature distribution was performed for variation of characteristics of a fiber Bragg grating. The fiber Bragg gating was fixed on a thermal head consisting of a microheater array. The temperature of each position of the fiber is varied with the temperature of each heater. A new control circuit was developed for serial digital data transmission to a thermal head. We used a thermal head with 576 microheaters and a 1.55μm nonchirped grating. Wavelength shift of 3.3 nm was obtained, and single reflection was changed to two-wavelength reflection with a separation of 1.7 nm by stepwise temperature distribution. For temperature slope, chirp of 1.4 nm was obtained. The temperature fluctuation, which may occur by data transmission, was confirmed to be negligible. This shows that the control was fast enough considering the heat capacity of the fiber.
