摘要:

双势垒共振隧穿二极管在单极光波导内的集成提供了宽带宽上的电增益。由于双势垒共振隧穿二极管引入的非线性效应,InGaAlAs/InP单极光波导既可用作光调制器,又可用作光探测器。模拟结果与初步实验结果一致,在1520 nm ~ 1600 nm波长范围内,器件的最佳调制深度可达23 dB,啁啾参数在-1 ~0之间。

英文摘要:

The integration of a double barrier resonant tunneling diode within a unipolar optical waveguide provides electrical gain over a wide bandwidth. Due to the non-linearities introduced by the double barrier resonant tunneling diode an unipolar InGaAlAs/InP optical waveguide can be employed both as optical modulator and optical detector. The modeling results of a device operating as optical modulator agree with preliminary experimental data, foreseeing for an optimized device modulation depths up to 23 dB with chirp parameter between -1 and 0 in the wavelength range analyzed (1520 nm - 1600 nm).
