Title: Optical tunable filter
Inventor: ENDO TAKASHI
IPC: H04J14/00
Filed: 1995-04-18
Abstract: PURPOSE: To simply select a prescribed transmitted wavelength by arranging a BPF in a collimated optical path in a freely oscillating way, and providing an optical filter control circuit controlling a tilt angle of the BPF, a channel input device and a channel storage circuit. CONSTITUTION: A steep transmitted spectrum is obtained from a BPF 4 even when its optical axis is tilted with respect to an optical axis of a collimated optical path, a linear way 8 is fitted to a tip of a piezoelectric actuator 7 formed by laminating piezo elements, and a tip roll 10 of a shaft 9 of the BPF 4 is pressed into contact with the linear way 8. The tilt angle of the BPF 4 is adjusted in response to the elongation/contraction amount of the actuator 7, an applied voltage to the actuator 7 is adjusted by an optical filter control circuit 6 to control the tilt angle of the BPF 4. When a transmitted wavelength is received from a channel storage circuit 3, the BPF 4 transmits only the transmitted wavelength. Furthermore, plural transmitted wavelengths are stored in the circuit 3 in advance and each channel number is assigned to each transmitted wavelength.
