碩士 === 元智大學 === 電機工程學系 === 90 === This dissertation focus on the research of using optical component to control and modulate the illuminant, light intensity and wavelength in tunable optical communication system. And the control method is to proceed linear control of the feedback voltage. Proceeding linear control of the feedback voltage mentioned in the text is to promote the changing quantity to achieve linearity when adjusting the illuminant, light intensity and wavelength.When devising the control rule, the controlling time is devided into three scales, which are acceleration, constant velocity, and deceleration, in order to have smoothly-operation of the motor and achieve the intention of precisely-control. Last but not least, I use this control method cooperating with optical system to experiment on optical communication system; the conclusion shows that the changing quantity of illuminant, light intensity and wavelength all achieve the intention of precisely-control with good effect.
