Patent number: 6229832Abstract: An optical transmitter includes a plurality of optical wavelength stability control apparatuses, each of which is capable of compensating for a wavelength drift by varying a laser diode drive current. Each of the optical wavelength stability control apparatuses detects a laser diode drive current, which is controlled by an auto power control circuit, by using a laser diode drive current detector. The laser diode drive current is normalized by a laser diode drive current increase/decrease normalization unit. A laser diode temperature control target value is generated at a compensated reference voltage generator, in response to the normalized laser diode drive current, to control a current value applied to a thermoelectric cooler so that an output value of a temperature monitor circuit approaches a predetermined laser diode temperature control target value.Type: GrantFiled: November 10, 1998Date of Patent: May 8, 2001Assignee: Hitachi, Ltd.Inventors: Naohiko Baba, Hideyuki Serizawa, Akihiro Hayami, Tadashi Hatano, Yasuhiro Yamada, Norio Chujo
