        摘要

        報道了InGaAs/GaAs/InGaP量子阱激光器的激光光譜研究,并在法布里-珀羅(FP)腔激光器中發現了單模工作特性,且該單模工作特性可以在較大的工作電流范圍內(36~68 mA)存在,在一定的電流(14 mA)范圍內保持單模可調諧。在20 ℃,當器件注入電流為62 mA時,激光器單模工作情況下的最大邊模抑制比(SMSR)為29.8 dB,在其他電流條件下該器件的邊模抑制比也都大于20 dB。激光器在單模工作時,器件最大輸出功率(單面)達到12.5 mW。對于具有相同結構和材料的FP腔激光器來說,在不同條寬或腔長的器件中都觀察到上述單模工作特性。這一特性在一些單頻激光的應用系統中具有較大的應用價值。

        Abstract

        In this study, we investigate the laser spectra of the InGaAs/GaAs/InGaP quantum well lasers. Single-mode operation characteristics can be observed in the Fabry-Perot (FP) cavity laser, which exist in a large operating current range (36-68 mA). Mode-hop free wavelength tuning can be observed at a current of 14 mA. The maximum side-mode suppression ratio (SMSR) under single-mode operation of the laser is 29.8 dB at 20 ℃ with an injection current of 62 mA, while SMSR values are generally greater than 20 dB under other injection currents. Furthermore, the maximum output power (single side) of the laser under single-mode operation reaches 12.5 mW. Accordingly, the aforementioned single-mode operation characteristics can be observed for the FP cavity lasers fabricated with similar structures and materials in devices exhibiting different strip widths and cavity lengths. This unique feature results in considerable application potential in applications requiring a single-frequency laser source.
