| 英文摘要 | An optical transmitter includes a plurality of optical wavelength stability control apparatus, each of which is capable of compensating a wavelength drift by varying the laser diode drive current. Each of the optical wavelength stability control apparatus detects the laser diode drive current, which is controlled by an auto power control circuit, by using a laser diode drive current detector (1). The laser diode drive current is normalised by a laser diode drive current increase/decrease normalisation unit (2). A laser diode temperature control target value is generated at a compensated reference voltage generator (3a, 3b), in response to the normalised laser diode drive current, to control the current value applied to a thermoelectric cooler (12) so that the output value of a temperature monitor circuit (10) approaches a predetermined laser diode temperature control target value. |
