| 英文摘要 | An optical transmitter includes a modulator (2) for generating a modulated current in accordance with a modulation control signal, a light emitting element (1) driven by the modulated current from the modulator to emit light in accordance with the modulated current, a first current source (3) for supplying the modulator with a driving current, a first temperature detector (6, 6A) for detecting an operating temperature of the modulator to output a signal indicative of a detected operating temperature of the modulator, and an amplifier (4) for receiving a data signal to supply the modulator with the modulation control signal based on the data signal. The amplifier has a first modulation control signal controller (I0, Q3-Q6) for controlling a changing amount per unit time of the modulation control signal at rising and falling times in accordance with an output signal of the temperature detector (6, 6A). |
