We design a competent gain-flattened and noise figure in L-band hybrid optical amplifier using a hybrid configuration with a Raman amplifier (Raman) and quantum-dot vertical-cavity semiconductor (QDVC-SOA) for a 400×20 Gbps super-dense wavelength division multiplexing system (SD-WDM) at channel spacing 100 GHz. The proposed hybrid optical amplifier (HOA) shows that it can be constituted into an optical amplifier-based subsystem, such that the Raman semiconductor optical amplifier (RAMAN-SOA), the erbium-doped fiber amplifier (EDFA-SOA), and an EDFA-EDFA with similar characteristics can flatten the gain for 100 GHz SD-WDM application; our investigation demonstrates a flat gain of 28.55 dB at 1597 nm. In addition, the highest value of flat gain, equal to 28.55 dB, is obtained from the Raman–QDVC-SOA HOA with a minimum variation of 1.4 dB from 1560 to 1630 nm. Further, the noise figure (0.5 dB) demonstrates the minimum value reported for a Raman amplifier–QDVC-SOA hybrid optical amplifier at channel spacing 100 GHz for the L-band, and this fact is experimentally demonstrated.

用于超高密度波分复用系统的级联拉曼量子点垂直腔半导体混合光放大器的L频带平坦的增益/噪声系数

我们设计了一种具有拉曼放大器（Raman）和量子点垂直腔半导体（QDVC-SOA）的混合配置的L波段混合光放大器，其增益平坦度和噪声系数为400 ×20 Gbps超密集波分复用系统（SD-WDM），信道间隔为100 GHz。提出的混合光放大器（HOA）表明它可以构成一个基于光放大器的子系统，例如拉曼半导体光放大器（RAMAN-SOA），掺b光纤放大器（EDFA-SOA）和EDFA -具有类似特性的EDFA可以使100 GHz SD-WDM应用的增益平坦；我们的研究表明，在1597 nm处平坦增益为28.55 dB。此外，从拉曼-QDVC-SOA HOA获得的平坦增益最大值等于28.55 dB，在1560至1630 nm之间的最小变化为1.4 dB。此外，噪声系数（0.5 dB）证明了在L波段的信道间隔为100 GHz时，拉曼放大器– QDVC-SOA混合光放大器报告的最小值，
