我们使用绝缘体上硅衬底制造了具有高光约束效应的光波导，并且我们消除了光学校准的困难，使激光通过对红外光透明的p-n同质结。激光从光波导的一个切割边引入，并被引导到透明的p-n同质结，并测量从另一个边缘发射的光的功率。因此，我们成功地以高精度评估了光学放大特性。对于波长为1.31µm的光，我们获得了差分增益系数g= 2.6 × 10−2cm/ a，透明电流密度jtr = 1 mA/cm2，饱和光功率密度psat = 30 kW/cm2。对入射光功率引起的增益饱和的观测表明，该测量方法适用于光放大性能的评价。
We fabricated an optical waveguide having a high optical confinement effect using a silicon-on-insulator substrate, and we eliminated the difficulty involved with optical alignment for making laser light pass through a p–n homojunction that is transparent to infrared light. Laser light was introduced via one of the cleaved edges of the optical waveguide and was guided to the transparent p–n homojunction, and the power of the light emitted from the other edge was measured. As a result, we successfully evaluated the optical amplification properties with high precision. For light with a wavelength of 1.31 µm, we obtained a differential gain coefficient ofg= 2.6 × 10−2cm/A, a transparency current density ofJtr= 1 mA/cm2, and a saturation optical power density ofPsat= 30 kW/cm2. The observation of gain saturation due to the incident optical power shows that this measurement method was suitable for evaluating the optical amplification properties.
