摘　　要：报道了一种波长可热调谐的电吸收调制分布反馈激光器(Electroabsorptionmodulateddistributedfeedbacklaser,EML)。在激光器条形的侧面淀积一薄膜加热器,EML实现了 2 2nm的连续调谐。在调谐范围内,激光器输出功率的变化小于 3dB。采用端面有效反射率方法和耦合波理论的计算表明:采用相调制方法,可实现调谐范围达3 2nm的EML。如果热调谐与相调谐方法结合。A new type wavelength tunable electroabsorption modulated DFB laser (T-EML) by using a thin-films heater is proposed and successfully fabricated. The EML tuning range amounts to 2.2 nm with a 3.8 nm/W tuning efficiency. In the tuning range, the EML output power variation is less than 3 dB, the extinction ratio variation is very little and the side mode suppression is maintained more than 30 dB. A wavelength fast tunable EML by using phase tuning is also proposed. By using the facet effective reflectivity method and the coupling wave theory, the tuning range of the phase tuning EML is about 3.2 nm from calculation. A wide range and fast tunable EML can be achieved by using thermal and phase tuning.
